How does a mutation occur

WebThere are many different ways that DNA can be changed, resulting in different types of mutation. Here is a quick summary of a few of these: Substitution A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such WebThe change to a person’s DNA during a somatic mutation happens after fertilization in any cell of their body that isn't a sperm or egg cell (germ cells). Cells continuously copy and replace themselves in humans. If a mutation occurs, all cells that form from that affected cell will have that mutation in its DNA. Conditions and Disorders
