Question

4 Why do most changes to DNA have no effect at all?

A Because they're too minor to have any effect B Because the changes are offset by RNA, which cannot change
C Because the changes are quickly repaired
D Because the changes only occur in a few cells​

Answer 1

C: The changes are quickly repaired.

Step-by-step explanation:

Numerous somatic mutations are not immediately harmful to an organism because genetically healthy body cells can make up for the mutated cells. The life and function of an organism can, however, be significantly impacted by a few other mutations. Numerous other mutations are repaired before protein synthesis takes place, so they have no impact on the organism. DNA mutations can be fixed by a variety of repair mechanisms in cells.
