Question

Observation of cells that are in the late stages of mitosis (prior to cytoplasmic division) shows that transcription has ceased. Describe TWO reasons for this.

Answer 1

In late stages of mitosis (prior to cytoplasmic division), the process of transcription ceases because:

1. In late phases of mitosis, the process of chromatin condensation occurs that also includes the transcription elements, so during that time RNA polymerase is not available to bring about transcription so it has to stop.
2. In the late cycle of division, Cell starts to prepare about the next replication round, so when the machinery for replication works, transcription slows down.
