when does dna replication occur in mitotic cell division?
There is G1 phase, S phase, G2 phase and mitosis phase in a cell division cycle. The DNA is synthesized in S-phase. There is no specific phase of DNA replication but in cell division we have. In mitosis phase we have prophase, metaphase, anaphase and telophase. DNA is replicated in synthesis(S) phase prior to start of prophase.
