Answer:
horizontal gene transfer
Explanation:
Horizontal Gene Transfer (HGT) can be defined as a non-sexual process that enables the exchange of genetic information between genomes. Although HGT mainly occurs between prokaryotic genomes, an increasing number of examples involving eukaryotic host genomes have recently been described. Agrobacterium bacteria are capable of transferring and integrating DNA into the genome of eukaryotic cell hosts by the HGT mechanism. The transference of genetic material via Agrobacterium-mediated transformation is widely used in biotechnology to generate plants with desired genetic sequences. In the last years, it has been shown that various bacterial species including Bartonella henselae Rhizobium etli or even Escherichia coli, are able to genetically transform eukaryotic cells under laboratory growth conditions. The genetic phenomenon of horizontal gene transfer has evolutionary significance since it enables to bypass barriers between kingdoms in order to acquire nucleotide sequences that may eventually have some adaptive advantage. Moreover, the mechanism of horizontal transfer challenges a narrow vision of the eukaryotic genome as a fixed entity.

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is dominant to dull (g) and Long (L) hair is dominant to short (l). You have a pair of dogs that you have been breeding for several years. The mom is glossy long haired and the dad is dull short haired. Over several litters they have produced the following puppies: 18 Glossy Short 16 Dull Long 8 Dull Short 6 Glossy Long What are the parental gametes produced by this mom
Answer:
GL, Gl, gL, and gl
Explanation:
The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:
GGLL, GgLL, GGLl, or GgLl
The dad is dull and short haired, the genotype would be ggll.
GGLL x ggll
Progeny = all GgLl (all glossy long haired)
GgLL x ggll
Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)
GGLl x ggll
Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)
GgLl x ggll
Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)
Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.
The parental gametes produced by the mom would be; GL, Gl, gL, and gl
2) The slight negative charge at one end of a water molecule is attracted to the slight
positive charge of second water molecule. What is this attraction/bond called?
A) a covalent bond
B) a hydrogen bond
C) an ionic bond
D) a hydrophilic bond
E) a hydrophobic bond
3) What gives rise to the cohesiveness of water molecules?
A) hydrophobic interactions
B) nonpolar covalent bonds
C) ionic bonds
D) hydrogen bonds
E) both A and C
Answer:
2. C
3. D
Explanation:
2. Ionic bonds are chemical bonds that forms between the ions of molecules or compounds. The two molecules are joined together by an electrostatic force. This is the case of the bond that forms between the slight negative charge (anion) at one end of a water molecule and the slight positive charge (cation) of a second water molecule.
3. Cohesion refers to the attraction of a molecule to a like molecule. The cohesiveness of water molecule to another water molecule is great due to the HYDROGEN BONDS that forms between them.

Answer:
What are the symptoms of Hypohidrotic ectodermal dysplasia?
Hypohidrotic ectodermal dysplasia (HED) is a genetic skin disease. Common symptoms include sparse scalp and body hair, reduced ability to sweat, and missing teeth. HED is caused by mutations in the EDA, EDAR, or EDARADD genes .
No, all the individuals who have the spongy tiny pore allele do not show it in their physical appearance.
Only those individuals in which this spongy tiny allele is dominant over other alleles will be appeared in their physical appearance whereas those individuals in which this allele is present as a recessive allele then it will not appear in their physical appearances so we can conclude that only dominant allele will appear in the physical appearance of an individual.

When you perform a three-point test cross to determine the linkage between three genes, you found that distance between the three genes were 16 and 8 map units. Of 1000 progeny produced in the test cross, you observe 7 double recombinants. What is the interference?
a. 0.547
b. 0.453
c. 0.16
d. 0.08
e. 0.0128
Answer:
The correct option is b. 0.453
Explanation:
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
• Observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals
• Expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.
CC= (7/1000)/0.16x0.08
CC= 0.007/0.0128
CC=0.5468
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.5468
I = 0.4531
three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle
Answer:
-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)
-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)
-termite’s feces help to prevent erosion
Explanation:
Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.

Explanation:
Meristamatic cells of onion root tip are displayed in the picture. This renders the most desirable and suitable raw material to study the different stages of mitosis.
What are meristematic tissue?A meristem is a particular kind of tissue that can be found in plants. It is made up of cells that have not undergone differentiation and are able to divide. Meristematic cells have the potential to differentiate into all of the other types of tissues and organs that can be found in plants. These cells will continue to divide until they reach a certain point, at which point they will begin to differentiate and will no longer be able to divide.
Additionally, meristematic tissue is responsible for the generation of secondary tissues like wood and cork. Both primary growth (expansion) and secondary growth (thickness) contribute to the plant's overall development.
Apical meristems are the cells that are responsible for the growth of the plant's primary body as well as the extension of its roots and shoots. Because they are the cells that are responsible for secondary growth, also known as an increase in stem girth and thickness, lateral meristems are also referred to as secondary meristems.

You are a new hire at a bioinformatics company and are helping to annotate the genome of a recently sequenced organism. A co-worker indicates that the software used to detect potential genes finds protein-coding genes more easily than genes for noncoding RNAs. What difference between coding and noncoding genes explains why genes coding for proteins are easier to identify than genes for noncoding RNAs
Answer:
A protein-coding gene has an open reading frame (ORF) that make easier its identification
Explanation:
During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.

Explanation:
What ensures that blood levels of a specific releasing hormone are locally high in order to stimulate the pituitary?
Answer:
The correct answer is: hypothalamic-pituitary portal system.
Explanation:
The hypothalamic-pituitary portal system, also called the hypophyseal portal system, is a system of blood vessels that connect the hypothalamus with the anterior pituitary to transport hormones between these two glands.
The hypothalamus and the anterior pituitary are a hugely important part of the endocrine system, since many hormones are secreted by these glands. Not only that but the hormones released by the hypothalamus have a direct effect on the hormones released by the anterior pituitary gland, which affects different peripheric glands as well. For example, the hypothalamus releases the thyrotropin-releasing hormone, which stimulates the anterior pituitary to release the thyroid-stimulating hormone, which stimulates the thyroid to secrete thyroid hormone. This sort of information between the hypothalamus and the anterior pituitary is transmitted thanks to the hypothalamic-pituitary portal system, which has fenestrated capillaries that allow an even faster exchange between the glands. If the blood in this portal system has high levels of, for example, the thyrotropin-releasing hormone, the anterior pituitary will soon start releasing the thyroid-stimulating hormone.
