Question

Quizplus · Accepted Answer

DNA damage refers to physical abnormalities in the DNA, such as breaks or chemical changes to bases, which can be repaired by cellular mechanisms. A mutation is a permanent alteration in the DNA sequence that remains after the DNA has been replicated. If DNA damage is corrected by DNA polymerase or other repair mechanisms before replication, it does not result in a mutation.
