Quizplus · Accepted Answer

Mutations are caused by random errors in DNA replication and other cellular processes. While exposure to certain types of radiation and chemicals can increase the likelihood of mutations, the exact location and type of mutation are unpredictable and random.

(Note: A, B, C, and E are all false statements.)
