When would a point mutation occur? It can occur before and after cell division
Before the cell divides
After the cell divides
Before DNA replication

The correct answer is option 1. Before and After Cell Division

Explanation:

Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations. But they may also occur after as well as before the division of a cell.

this is a good question! i'll do some research and come back when i have the answer!
