Question

Our DNA is subject to mutations on a daily basis. Why do most mutations that occur in the genome of organisms escape detection and not elicit a deleterious

Answer 1

Ans:

The Mutation is defined the alteration in the sequences of DNA.The mutation can be calssified into two types:

1. Herediarty mutations:

This type of mutation occurs as same in the parent organism.This type of mutation occurs in every cells of body. and it can be detect in screening because the changes or alteration occurs in every cell.

2. Acquired(Somatic ) Mutations:

This type of mutations occurs due to external factors like environmental factor which includes climate , Ultravoilet radiations etc. This type of mutations starts from a change or alteration in single cell of the body .That deleterious mutation can not be detected in screening because it starts from single cell.

Thus the detection of mutation escaped only incase where mutation is acquired or somatic types only.
