Understand that interphase is a part of the cell cycle where the cell prepares for division. It is not a phase of mitosis or meiosis itself, but rather the phase where the cell grows and duplicates its DNA.
Recognize that interphase consists of three stages: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). Each stage has specific functions that prepare the cell for division.
During the G1 phase, the cell grows and performs normal functions. It also prepares the necessary components for DNA replication.
In the S phase, DNA replication occurs. This is the process where the cell duplicates its DNA, ensuring that each daughter cell will have a complete set of chromosomes after cell division.
The G2 phase follows DNA replication, where the cell continues to grow and prepares for mitosis. It checks for DNA errors and begins to form the structures necessary for chromosome segregation during mitosis.
