Summary Introduction
Introduction:
The eukaryotic cell cycle consists of four phases, mainly G1, G2, S, and M phases. These phases occur during cell division and help the cell to divide accordingly. There are two gap phases (G1 and G2) and a synthesis phase (S phase). M phase is the partition phase, where the cell divides itself into two daughter cells.
