Question

Quizplus · Accepted Answer

A DNA mutation is a permanent change in the nucleotide sequence of DNA. This can occur from errors during replication, exposure to mutagenic agents, or spontaneous errors in DNA synthesis. The result is a change in the genetic code, which can lead to altered protein function and potentially harmful effects on an organism.
