Question

What can cause mutations?

Answer 1

Mutations occur due to errors during replication, damage to DNA, or an error prone repair in DNA.

Explanation:

DNA replicates itself during the process of growth and repair of the body cells. During this process of duplication, errors may occur. Most mutations occur when the cell makes error as it copies its genes.

Chemicals and radiations can damage DNA. Thus mutations can also be caused by exposure to specific chemicals or radiations.
