Cell cycle can be defined as the the movement of cell through various phases in a cyclic manner to prepare itself for division .This cyclic movement of cell is termed as cell cycle.

Explanation:

Cell cycle basically composed of 2 phases

1 Interphase: It contain 3 subphases

a G1 Phase which deals with the synthesis of RNA and protein.

b  S Phase  which deals with DNA replication.

c  G2 phase which deals with synthesis of RNA and proteins.

2  Mitotic phase: it contain 4 sub phases

a Prophase chromosome condensation along with disappearance of nuclear envelop and nucleolus.

b Metaphase  Arrangement of chromatid in the equatorial plane or metaphase plate.

c Anaphase  movement of chromatids toward the opposite poles of the cells .

dTelophase Reappearance of nuclear envelop and nucleolus in the

newly formed daughter cell with equal number of chromosome in bth cells

Regulation of cell cycle

Cell cycle is regulated by variousfactors such as

1  Maturation promoting factor( MPF) this protein helps in the movement of cell from G2 to M phase.

2 G1  cyclin CDK These proteins helps in the transition of cell from G1 phase to S phase.

3 S cyclin CDK  These proteins helps in the transition of cell from Sphase to G2 phase.
