A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis)within a sin
Shalnov [3]

True

Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.

Explanation:

The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of  several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.

Which two globin genes are most divergent from each other? what is the percent amino acid identity between them?
tiny-mole [99]

Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
