Answer:
Explanation:
DNA polymerases are the enzymes that build DNA in cells. DNA polymerase also proofread their work to check for any error the process of which is called proof reading.
If the polymerase detects that an Incorrectly paired nucleotide has been added, it will remove (splicing) and replace the nucleotide with the correct one before it continues with DNA synthesis.
Mismatch repairing also corrects other errors that omit proofreading. They fix mismatched base pairs, replace some insertion and deleted base pair that can result into mutations.
When an error is corrected the rate of mutation is reduced this is because mutation results from error during the DNA formation process either through Insertion of a wrong nitrogenous base, or deletion leading to formation of an entirely new amino acid sequence that result into abnormal phenotype.
Stage 1 which is the high fluctuating stage has both high birth rates and high death rates.
<h3>What is Famine?</h3>
This is a condition which is characterized by lack of food as a result of some factors such as war, natural disaster etc.
In the stage 1, the population growth is slow and fluctuating as a result of high incidences of disease and famine.

In general, coding regions are more likely to have the same sequence. It is more likely to produce a non-functional gene product (protein).
Non-coding mutations are free to mutate because it has no protein product, and are less likely to affect phenotype. They are neutral mutations. Different mutations can be differentiated even when different groups have the same coding sequence.
Answer:
The Mark B is the tRNA in the illustration
Explanation:
The process of translation requires four significant components within the cell
1. The mRNA, which is a product of transcription from the cells RNA or DNA, depending on the genetic part of the cell, as some cells have RNA while others have DNA. It bears the exons for the process of translation. Thus it is usually attached to the ribosome during the process of translation. This is mark A.
2. The tRNA, which generally forms a loop with one end used for the attachment of the right amino acid coded on the mRNA triplet codons. The illustration given in the question shows that the structure mark B is attached to Glycine. This showed that the structure is the tRNA.
3. The ribosome is the main structure where protein is being synthesized; it housed the mRNA and permit the input of the right amino acid for the formation of peptide bonds.
4. Amino acids are also essential for the production of protein during translation.
