The Cell Cycle Periods

The cell cycle is a series of events that occur in a cell leading to its division and the production of two daughter cells. It consists of several distinct phases or periods. Here are the main periods of the cell cycle:

1. Interphase: Interphase is the longest period of the cell cycle and can be further divided into three phases: G1, S, and G2.

- G1 phase (Gap 1 phase): During this phase, the cell grows and carries out its normal functions. It prepares for DNA replication and checks for any DNA damage or errors. The cell also determines whether it is ready to proceed to the next phase of the cell cycle. - S phase (Synthesis phase): In this phase, DNA replication occurs. The cell duplicates its DNA to prepare for cell division. Each chromosome is replicated, resulting in two identical copies called sister chromatids. - G2 phase (Gap 2 phase): During this phase, the cell continues to grow and prepares for cell division. It checks
