What follows the G1 phase in the cell cycle?

The correct answer is S phase, which follows the G1 phase in the cell cycle. During the G1 phase, the cell grows and prepares for DNA replication. It also carries out its normal metabolic functions. Once the cell has completed this phase, it enters the S phase, where DNA synthesis occurs. This is the critical point where the cell duplicates its genetic material in preparation for cell division.

Following the S phase, the cell will proceed to the G2 phase, which is focused on further growth and preparation for mitosis, including the synthesis of proteins necessary for cell division. Understanding the sequential progression from G1 to S phase reveals the organized nature of the cell cycle and how each phase plays a specific role in ensuring proper cell division and function.
