DNA Mutations

Question 3 • [HSBIO] Biology, Sem 1 (26-27)

Which best describes somatic mutations?

Answer
A
They are usually passed on to offspring.
B
They can cause different kinds of cancer.
C
They always result from point mutations.
D
They only occur in reproductive cells.

Explanation

Somatic mutations occur in body cells rather than reproductive cells, so they are generally not passed on to offspring. If they affect genes that control cell growth, they can contribute to different kinds of cancer. They are not limited to point mutations, and mutations in reproductive cells are called germline mutations.
