Interphase
Interphase is a stage in the cell cycle that occurs before cell division
Interphase is a stage in the cell cycle that occurs before cell division. It is the period during which the cell grows, carries out its normal functions, and prepares for cell division. Interphase can be divided into three phases: G1 phase, S phase, and G2 phase.
During the G1 phase, the cell undergoes growth and carries out its normal metabolic activities. It increases in size, produces proteins, and synthesizes RNA. This phase is also called the “gap phase” because it represents a gap between the previous cell division and the initiation of DNA replication.
After the G1 phase, the cell enters the S phase. In this phase, the cell’s DNA is synthesized or replicated. Each chromosome is duplicated and its two copies, called sister chromatids, are attached to each other. DNA replication ensures that each new cell formed during division will have a complete set of genetic information.
Following the S phase, the cell enters the G2 phase. During this phase, the cell prepares for division by further growing in size and synthesizing more proteins. The G2 phase serves as a checkpoint to ensure that DNA replication has been completed accurately and that the cell is ready for division.
Overall, interphase is a critical stage in the cell cycle as it allows the cell to grow, perform necessary functions, and prepare for division. It provides the necessary time for synthesis of materials required for cell division to occur successfully. Without interphase, the cell would not have enough time to grow and prepare adequately, potentially leading to errors and abnormalities in cell division.
