Cell Cycle & Mitosis
The cell cycle is the division of somatic cells. They divide so that the cell can grow, so that the dead or damaged cells get replaced, and certain cells can be specialized. The first 3 phases of the cell cycle are G1, G2, & S (also called the interphase). The last two phases are Mitosis then cytokinesis.
First 3 Cell Stages.
Each stage of the cell cycle has a specific job. During G1, the cells grow quickly and it synthesizes proteins in preparation for mitosis. During the S phase, the DNA is copied so that there will not be any cell death or disease.
