According to the central dogma of molecular biology, DNA does this error originate.
What are the functions of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
DNA is made of nucleotides. A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases.

Mr. Brown is making a terrarium for his classroom so students can observe lizards. The terrarium has clear plastic sides so the students can see the lizards. He puts several tree branches and leafy plants in the terrarium. The lizards he is considering are adapted to different environments, and their feet have different features. These features are described in the following list.
Type 1: feet with large pads that spread out weight
Type 2: feet with webs of skin between the toes
Type 3: feet with short toes and sharp claws
Type 4: feet with tiny pads that act like suction cups
Based on the descriptions of the lizards' feet, which type is best adapted to Mr. Brown's terrarium?
Answer:
Type 4

In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.
Explanation:
A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.
each square would have 25% each because 100%÷4=25.
Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.
Blue is recessive.
The percentage of the Ss is 75% while the percentage of the ss is only 25%.
Performing a crossGiven that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.
Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Research on laboratory rats suggests that hunger is controlled by the
A. prefrontal cortex
B. hypothalamus
C. amygdala
D. cerebellum
Please select the best answer from the choices provided
Answer:
b hypothalamus
Explanation:
The hypothalamus controls hunger and satiety. Therefore, option (B) is correct.
What is the role of hypothalamus?
The hypothalamus regulates circadian rhythms, appetite, thirst, and body temperature. The study of illnesses and diseases associated to the neuroendocrine system may benefit from using rat hypothalamic neurons.
The arcuate nucleus, or infundibular nucleus in humans, is a region of the hypothalamus that permits peripheral peptides and proteins to cross the blood-brain barrier and interact with its neurons.

Answer give in Nepali How carbon dioxide is necessary for photosynthesis
❤----------------------------------------------------------------------------------------------------------❤
Carbon dioxide is necessary for photosynthesis in plants. It is so necessary because it combines with water to form glucose or carbohydrates which are incredibly important for plants to provide energy. If they were to not take in carbon dioxide, then they would also not give oxygen which is the most essential for humans.

what is the genotype
Answer:
XnXn
Explanation:
The female has inherited one X chromosome with the hemophilia trait and has inherited one X chromosome with the hemophilia trait from her father. We know her genotype must be XnXn because she needs two X chromosomes with the hemophilia trait to physically have the hemophilia trait, this is because hemophilia is recessive.

Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP.Based on these observations, which of the following conclusions would the scientists most likely draw?
A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription
B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes.
C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription
D. Ankrd 1 is binding to chromatin, recruiting proteins that remove acetyl groups, and silencing transcription of that region of DNA.
Answer: A- Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription.

C. Panels are set up to absorb solar energy.
D. Mountaintops are blown up to mine coal.
In an ecosystem, the statement which describes one way that a nonrenewable energy resource is obtained is that mountaintops are blown up to mine coal.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
