Identify the stages in the eukaryotic cell cycle, describe their principal events, and point out some ways in which the cycle is controlled.

The cell cycle consists of events that begin with the birth of the cell and end with the division on the cell. Interphase is the longest cell phase, and includes three subphases: G1 phase - the growth of the cell, S Phase- the DNA replication and G2 phase - additional  growth of the cell. 
 And then is the M Phase , which includes mitosis - the division of the mother cell into two daughter cells genetically identical to each other.
