Which of the following does not occur in the S phase of the cell cycle?
Open in App
Solution
The correct option is D Nuclear Division
The correct option is D.
The explanation for the correct option:
- S phase is a synthesis phase in which DNA replication takes place in a cell cycle.
- It occurs between G1 and G2 phases.
- Option d is correct because the S phase is a preparatory phase where genetic material replicates to undergo nuclear division in the M phase.
The explanation for the incorrect option:
Option A
DNA replication, histones synthesis, and nucleosome replication all occur in the S phase of the cell cycle.
Option B
DNA replication, histones synthesis, and nucleosome replication all occur in the S phase of the cell cycle.
Option C
DNA replication, histones synthesis, and nucleosome replication all occur in the S phase of the cell cycle.
Final answer: Nuclear division does not occur in the S phase of the cell cycle.
