What is One Reason Why Many Mutations May Be Deleterious

Question

What is one reason why many mutations may be deleterious?
A)Because the genetic code has redundancy built in.
B)Because if a mutation changes the primary structure of a protein, the protein may no longer work.
C)Because the body has no way to detect or correct mutations.
D)Most mutations are actually beneficial, not deleterious.
E)Any change in the DNA sequence means that DNA no longer functions properly.

Accepted Answer

Mutations that change the primary structure of a protein can have deleterious effects because the protein may no longer be able to perform its function properly. This can lead to a variety of issues in organisms, such as developmental abnormalities or disease.
