Get the answer of: How Many Stages are in Mitosis ? 1. Prophase: The DNA in the diffuse chromatin of the resting nucleus in interphase has been duplicated in S phase preceding this cell division. The extended state of interphase chromatin allows transcription and replication of DNA, but is not suitable for division into two daughter cells. Therefore, prophase, the [...]
