Question at position 36 DNA is replicated during the __________ subphase of interphase of the cell cycle.G1G2SM

Question

BlackTom AI · Accepted Answer

In this question, the cell cycle phases are being matched to the event of DNA replication.
Option 1: G1 — This phase involves cell growth and normal metabolic activities, but DNA replication does not occur here. So this option is incorrect for the context of replication.
Option 2: G2 — This phase comes after DNA replication, preparing the cell for mitosis. Since replication has already occurred by this point, G2 is not the subphase where replication happens. This makes the option inaccurate for the given statement.
Option 3: S — The S (synthesis) phase is specifically the period when DNA replication takes place, duplicating the genetic material in preparation for cell division. This aligns exactly with the described event.
Option 4: M — Mitosis is the division of the nucleus following DNA replication, not the phase during which replication occurs. Therefore, this choice does not describe the replication subphase.
