The reading assignment for this week introduced you to the four types of biological macromolecule.



For each category of macromolecule, carbohydrate, lipid, protein and nucleic acid, select a representative polymer and explain its function within the cell. Suggest which aspects of your chosen molecule are characteristic of the class of macromolecules to which it belongs by identifying its monomer subunits and describing their basic chemical structure and the manner in which the monomers are linked together.


For instance, an example of a carbohydrate would be cellulose. Its monomer subunit is glucose which is a monosaccharide with the formula C6H12O6. The glucose molecules in cellulose are linked together by β1-4 glycosidic bonds which form long chains and give cellulose its strength and rigidity. This strength is important as the function of cellulose is to provide structural support in plants

Answers

Answer 1

Carbohydrates are one of the four types of biological macromolecules, and one of their representative polymers is glycogen. Glycogen is a large, branched polymer made up of glucose monomers linked together by α1-4 glycosidic bonds and α1-6 glycosidic bonds.

Glycogen is primarily found in animal cells and serves as a storage molecule for glucose, providing a readily available source of energy for the cell. The branching structure of glycogen allows for quick and efficient access to glucose when it is needed by the cell.

Lipids are another type of macromolecule, and one representative polymer is triglycerides. Triglycerides are made up of three fatty acid molecules linked to a glycerol molecule by ester bonds. The fatty acid molecules vary in length and degree of saturation, giving triglycerides a wide range of physical properties. Triglycerides serve as a storage molecule for energy and are found in adipose tissue. They also serve as a structural component of cell membranes and play a role in cell signaling.

Proteins are a third type of macromolecule, and one representative polymer is hemoglobin. Hemoglobin is a complex protein made up of four subunits, each of which contains a heme group. Hemoglobin is responsible for transporting oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs. The subunits of hemoglobin are linked together by various types of chemical bonds, including hydrogen bonds, disulfide bonds, and hydrophobic interactions.

Nucleic acids are the final type of macromolecule, and one representative polymer is DNA. DNA is made up of nucleotides, which consist of a nitrogenous base, a sugar molecule, and a phosphate group. The nitrogenous bases are adenine, thymine, guanine, and cytosine, and they are linked together by hydrogen bonds to form the rungs of the DNA ladder. The sugar molecules and phosphate groups make up the sides of the ladder, linked together by phosphodiester bonds. DNA serves as the genetic material of the cell, carrying the instructions for the synthesis of proteins and other molecules necessary for cell function.

Overall, the monomer subunits and manner of linkage of each representative polymer are characteristic of the class of macromolecules to which it belongs. Carbohydrates are made up of monosaccharides linked by glycosidic bonds, lipids are made up of fatty acids linked to a glycerol molecule by ester bonds, proteins are made up of amino acids linked by peptide bonds, and nucleic acids are made up of nucleotides linked by phosphodiester bonds. These characteristics allow each class of macromolecules to perform their unique functions within the cell.

I need help finding the alleles

Answers

Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium. Frequency of dominant allele: 0.52. Frequency of recessive allele: 0.48. % homozygous dominant: 27%. % heterozygous: 50%. % homozygous recessive: 23%

What is Hardy-Weinberg equilibrium?

The Hardy-Weinberg equilibrium is a theory that states that the allelic and genotypic frequencies in a population in equilibrium remain the same generation after generation.

Populations in H-W equilibrium are not evolving.

Assuming a diallelic gene,

The frequency of the dominant allele p(X) is pThe frequency of the recessive allele p(x) is q

The addition of the allelic frequencies equals 1

p + q = 1.

The genotypic frequencies after one generation are

p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example, the frequency of the homozygous dominant genotype is given.

frequency of the homozygous dominant genotype

p² = 27% = 0.27

From this information, we can get the frequency of the dominant allele by taking the root square of the value.

dominant allele frequency

p² = 0.27

p = √0.27

p = 0.52

Now, we can clear the equation p + q = 1 and the get recessive allele frequency.

recessive allele frequency

p + q = 1

0.52  + q = 1

q = 1 - 0.52

q = 0.48

Now, we can get the frequency of the homozygous recessive genotype and the heterozygous one.

frequency of the homozygous recessive genotype

q = 0.48

q² = 0.48²

q² = 0.23

frequency of the heterozygous genotype

2pq = 2 x 0.52 x 0.48

2pq = 0.5

p² + 2pq + q² = 1

0.27 + 0.5 + 0.23 = 1

Frequency of dominant allele: 0.52Frequency of recessive allele: 0.48% homozygous dominant: 27%% heterozygous: 50%% homozygous recessive: 23%

Answers

The purine/pyrimidine ratio in the complementary strand of the DNA molecule is 1/0.6 or approximately 1.67.

1. Understand that the purine bases are adenine (A) and guanine (G), and the pyrimidine bases are cytosine (C) and thymine (T).
2. Know that the complementary bases pair up in DNA as A-T and C-G.
3. Given the purine/pyrimidine ratio of 0.6 for one strand, it means that for every 0.6 purines (A, G), there is 1 pyrimidine (C, T).
4. Since the complementary bases pair up in DNA, the number of purines in one strand equals the number of pyrimidines in the complementary strand, and vice versa.
5. So, if the given strand has 0.6 purines per 1 pyrimidine, then the complementary strand will have 1 purine per 0.6 pyrimidines.

Fruit flies of the species drosophila melanogaster are an important model organism for eukaryotic genetics. The genes for olive body color and purple eye color are on the same chromosome. Consider an organism with the chromosomes in the diagram above. What process is capable of producing a gamete with the alleles po?.

Answers

The process capable of producing a gamete with the alleles po in an organism with the chromosomes for olive body color and purple eye color on the same chromosome is crossing over or recombination.

Crossing over occurs during meiosis when homologous chromosomes exchange genetic material, resulting in new combinations of alleles on the chromosomes. This process can occur between the genes for olive body color and purple eye color if they are located on the same chromosome.

In the case of the diagram provided, the olive body color and purple eye color genes are located on the same chromosome, but they are not directly next to each other. This means that crossing over is possible between these genes, but the probability of a crossover event occurring between them is lower than if they were located closer together.

If a crossover event does occur between the olive body color and purple eye color genes, it can result in a gamete with the alleles po, which would be a new combination of alleles not present in either parent. This process of crossing over and recombination is important in generating genetic diversity within populations and is a fundamental mechanism of evolution.

A wolf is heterozygous for these two alleles displays a gray coat. Is it possible to produce a line of pure-breeding gray wolves? Why or why not?



Incomplete dominance: blended traits

Answers

No, it is not possible to produce a line of pure-breeding gray wolves. The reason is that gray coat color results from the incomplete dominance of the white coat and black coat alleles.

Incomplete dominance occurs when the traits of two alleles blend together, resulting in a different phenotype than either parent.
No, it is not possible to produce a line of pure-breeding gray wolves. The reason is that gray coat color results from the incomplete dominance of the white coat and black coat alleles.
When a wolf is heterozygous for these two alleles (one white coat allele and one black coat allele), it displays a gray coat. To create a line of pure-breeding gray wolves, you would need both alleles to be gray. However, gray is not a separate allele; it is the result of incomplete dominance between white and black coat alleles.

Therefore, any mating of gray wolves would still produce offspring with a mix of white, black, and gray coat colors, depending on the combination of alleles passed down to the offspring.

A scientist is studying a population of 100 lizards. Find the chi-square of AA=75 observed, Aa=15 observed, aa=10 observed

Answers

The chi-square value for the observed genotype frequencies for a population of 100 lizards is approximately 161.63.

To find the chi-square value for the observed values of the genotypes (AA = 75, Aa = 15, aa = 10) in a population of 100 lizards, we need to compare them with the expected values under a specific hypothesis.

First, we need to determine the expected genotype frequencies based on a specific hypothesis or assumption. Let's assume that the population is in Hardy-Weinberg equilibrium, which assumes random mating and no evolutionary forces at play. In that case, the expected genotype frequencies can be calculated based on the allele frequencies.

Let's assume that the allele frequencies are p and q, where p represents the frequency of the dominant allele (A) and q represents the frequency of the recessive allele (a). In a population in Hardy-Weinberg equilibrium, the expected genotype frequencies can be calculated as follows:

AA = p² * total population

Aa = 2pq * total population

aa = q² * total population

Since we don't have the allele frequencies, we cannot calculate the exact expected values. However, let's assume that the allele frequencies are p = 0.6 and q = 0.4.

Expected genotype frequencies:

AA = (0.6)² * 100 = 36

Aa = 2 * 0.6 * 0.4 * 100 = 48

aa = (0.4)² * 100 = 16

Now, we can calculate the chi-square value using the formula:

chi-square = Σ ((observed - expected)² / expected)

chi-square = ((75 - 36)² / 36) + ((15 - 48)² / 48) + ((10 - 16)² / 16)

chi-square = (39² / 36) + (33² / 48) + (6² / 16)

chi-square = 136.5 + 22.88 + 2.25

chi-square = 161.63

Therefore, the chi-square value for the observed genotype frequencies is approximately 161.63.

Which pair of terms correctly matches a cell or group of cells with its ability to differentiate into different specialized cells?.

Answers

The pair of terms that correctly matches a cell or group of cells with its ability to differentiate into different specialized cells is a) fertilized egg: pluripotent.

Pluripotent cells have the ability to differentiate into almost any cell type in the body, including cells of all three primary germ layers: endoderm, mesoderm, and ectoderm. The fertilized egg, or zygote, is the earliest stage of development and is considered pluripotent because it has the potential to differentiate into all the cell types of the body.

Totipotent cells have the ability to differentiate into all cell types, including embryonic and extraembryonic tissues. Ectoderm is one of the three primary germ layers that gives rise to various tissues, including the skin and nervous system. It is not totipotent but is rather multipotent, meaning it can differentiate into a limited number of cell types.

Endoderm and mesoderm are also primary germ layers that give rise to various tissues and organs in the body. Endoderm is multipotent, meaning it can differentiate into a limited number of cell types, while mesoderm is pluripotent, meaning it has the potential to differentiate into a wide range of cell types.

Answers

When a sound wave encounters air of a different temperature, the correct answer is (A) The sound wave changes speed and direction, bending away from the denser air and towards less dense air.

A sound wave is a type of mechanical wave that is created by the vibration or disturbance of matter. It is characterized by the transfer of energy through compressions and rarefactions of the medium it travels through. Sound waves can propagate through various mediums, including air, water, and solids.

Changes in temperature can cause variations in air density. Sound waves travel at different speeds in the air with different densities. When a sound wave moves from an area of higher air density (cooler air) to an area of lower air density (warmer air), it slows down and changes direction, bending away from the denser air and towards the less dense air. This phenomenon is known as refraction.

Therefore, the correct answer is (A) The sound wave changes speed and direction, bending away from the denser air and towards less dense air.

What happens if the birth rate in a population is more than the death rate? What happens if it is less?

Answers

Answer:

If the birth rate in a population is more than the death rate, then the population will grow over time. This means that there will be more individuals in the population and more demand for resources such as food, water, and space. If the birth rate in a population is less than the death rate, then the population will shrink over time. This means that there will be fewer individuals in the population and less competition for resources. However, if the population becomes too small, it may face extinction due to genetic drift, inbreeding, or environmental changes.

Natural increase happens when there are more births than deaths. Natural decrease means there were more people dying than babies born in a particular population. Areas with large aging populations often experience natural decrease and shrinking populations in the absence of migration

A population of chipmunks migrated to an environment where they had little competition. Their population quickly increased but eventually stabilized as shown in the graph.
Which statement best explains why the population stabilized?

The population size became limited due to factors such as availability of food.

Interbreeding between members of the population increased the mutation rate.

An increase in the chipmunk population caused an increase in the producer population.

A predator species came to the area and occupied the same niche as the chipmunks.

Answers

The best explanation for why the population stabilized is that the population size became limited due to factors such as availability of food. As the population of chipmunks increased, the availability of resources became limited, and the competition for resources increased. This eventually led to a decrease in the growth rate of the population until it stabilized at a certain level that the environment could support. This is a common phenomenon in ecological systems, where the carrying capacity of an environment limits the population size of a species.

Hope that helps! Good luck! :)

A population of squirrels in a remote forest may be gray (dominant) or brown (the recessive phenotype). Gray squirrels have the genotype GG or Gg. Brown squirrels have the genotype gg. The frequency of the GG genotype is 0. 30.



What is the frequency of heterozygous squirrels?




What is the frequency of the G allele?




What is the frequency of the g allele?

Answers

The frequency of heterozygous squirrels (Gg) is approximately 0.495.
The frequency of the G allele is approximately 0.55.
The frequency of the g allele is approximately 0.45.

In order to find the frequency of heterozygous squirrels (Gg) and the frequency of the G and g alleles, we can use the Hardy-Weinberg equilibrium formula, p^2 + 2pq + q^2 = 1, where p is the frequency of the dominant allele (G) and q is the frequency of the recessive allele (g).

Given that the frequency of the GG genotype is 0.30, we can determine p^2 = 0.30. To find p, we take the square root of 0.30, which is approximately 0.55.

Since p + q = 1, we can find the frequency of the g allele (q) by subtracting the frequency of the G allele (p) from 1: q = 1 - p = 1 - 0.55 ≈ 0.45.

Now that we have the frequencies of both alleles, we can find the frequency of heterozygous squirrels (2pq): 2(0.55)(0.45) ≈ 0.495.

In summary:
- The frequency of heterozygous squirrels (Gg) is approximately 0.495.
- The frequency of the G allele is approximately 0.55.
- The frequency of the g allele is approximately 0.45.

Which of these explains the change in energy of the rubber bands as they are relaxed when the student brings his hands closer together?
A The amount of kinetic energy is decreased.

B The amount of potential energy is increased.

C Potential energy converts to kinetic energy.

D Kinetic energy converts to potential energy

Answers

The change in energy of the rubber bands as they are relaxed when the student brings his hands closer together is due to the conversion of kinetic energy to potential energy.

Here correct answer is D.

As the student brings his hands together, the rubber bands are stretched and their motion is slowed down. As a result, the kinetic energy of the rubber bands is decreased and the potential energy increases. The potential energy of the rubber bands increases as the amount of strain on the bands increases.

As the student brings his hands closer together, the strain on the rubber bands increases and more potential energy is stored in the rubber bands. As the student's hands move closer, the kinetic energy of the rubber bands is gradually converted to potential energy.

Eventually, when the student's hands are fully together, all of the kinetic energy has been converted to potential energy and the rubber bands are at rest.
