Question

mutations within an organism can occur in body cells or reproductive cells. which type of mutation is seen in a sperm cell but not in a skin cell?
○ somatic mutation
○ missense mutation
○ nonsense mutation
○ germline mutation

Explanation:

1. First, recall the definitions:

• Somatic mutations occur in body cells (like skin cells) and aren't passed to offspring.
• Missense and nonsense mutations are types of point mutations (affecting DNA code, can occur in any cell with DNA, including body or reproductive cells).
• Germline mutations occur in reproductive cells (like sperm or egg cells) and can be passed to offspring. Since skin cells are body cells, germline mutations are in sperm (reproductive) but not skin (body) cells.

Answer:

D. germline mutation
