Mutations are changes in an organism’s DNA sequence that can alter how genes work.

Example 1: A single base change in the hemoglobin gene can cause sickle cell disease.
Example 2: A mutation in a bacterial gene can make the bacterium resistant to an antibiotic.

Mutations in biology create genetic variation that evolution can act on.
