Detailed explanation-1: -1 Answer. if it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.
Detailed explanation-2: -Mutations can occur during many points of a cell’s life cycle-during DNA replication, during Interphase as a result of some environmental factor, or during expression of DNA as cells make proteins.
Detailed explanation-3: -Some mutations occur when a mistake is made during DNA replication or transcription. Other mutations occur because of environmental factors.
Detailed explanation-4: -According to the classic view, most mutations arise in dividing cells and result from uncorrected errors of S-phase DNA replication, which is highly accurate because of the involvement of selective DNA polymerases and efficient error-correcting mechanisms.
