Question

Explanation:

Mutations are changes in an organism's DNA sequence. Silent mutations, for example, have no impact on the resulting protein. Beneficial mutations can improve an organism's survival or reproductive fitness, like antibiotic resistance in bacteria. Harmful mutations can cause genetic disorders or reduce fitness, such as mutations leading to cystic fibrosis. Thus, mutations can fall into all three categories.
