Question

1. What role does control of gene expression play in the diversity of individuals of the same species within a population, and how does this individual diversity contribute to natural selection?
2. Point mutations within the DNA are often considered neutral, in that they have no discernable effect on the phenotype of the affected individual. Why is this the case? What properties of the genetic code contribute to the neutrality of point mutations?
3. Why are mutations that add or subtract nucleotides within the DNA so detrimental to the health of an individual?

Answer 1

SOLUTION → Genes play a coucial role in encoding proteine and Conteral of these processes plays critical role in determining which proteins are present in a cell and ui what quauility. + OH is usually cont 910.lled at the level of trans coupton to avoid ovqexpression of genes causing unnecessary changes in gevetic foramework → As we know, natural selection leads to speciation which gives use to new and distinctly different species. These individuals douive evolution and get adapted to their envisionments which promotes natural selection.
