Definition
Interphase is the phase of the cell cycle during which a cell prepares for division, consisting of three stages: G1 (Gap 1), where the cell grows and synthesizes proteins; S (Synthesis), where DNA is replicated; and G2 (Gap 2), where the cell continues to grow and prepares for mitosis.
Summary
Interphase is a crucial part of the cell cycle, consisting of three distinct phases: G1, S, and G2. During G1, the cell grows and prepares for DNA replication, while in the S phase, the DNA is replicated to ensure that each daughter cell will have a complete set of chromosomes. The G2 phase involves further growth and preparation for mitosis, including error checking to maintain genetic integrity. Understanding interphase is essential for grasping how cells function and divide. It plays a significant role in various biological processes, including development, tissue repair, and cancer progression. By studying interphase, we can gain insights into cellular behavior and the implications of errors in the cell cycle, which can lead to diseases such as cancer.
