Interphase is not a period of rest, but a time of intense activity where the cell:
* Grows: The cell increases in size and produces new organelles and cytoplasm.
* Replicates DNA: The genetic material is copied to ensure each daughter cell receives a complete set of chromosomes.
* Prepares for division: The cell synthesizes proteins and other molecules necessary for mitosis or meiosis.
Interphase is divided into three phases:
* G1 (Gap 1): The cell grows and carries out normal functions.
* S (Synthesis): DNA replication occurs.
* G2 (Gap 2): The cell prepares for mitosis or meiosis, synthesizing proteins and organelles.
After interphase, the cell enters the mitotic or meiotic phase, where it divides into two or four daughter cells, respectively.
