What occurs in each 3 main stages of cell cycle?

Answer 1

The three main stages of cell cycle are interphase, mitosis and cytokinensis.

Interphase is made up of three stages - G1, S, and G2

G1 phase - The first phase of the cell cycle

The cell prepares itself for the synthesis stage of the cell cycle. The cell checks to see if it has all materials required for synthesis.

S phase - the DNA is copied so that at the end of this cycle each daughter cell has a complete set of chromosomes.

G2 phase - The second growth phase of the cell cycle

In this phase the cell prepares itself for physical separation of the cell to form two daughter cells.

Mitosis

In this phase the pairs of chromosomes attach themselves to fibers that pull the sister chromatids to the opposite sides of the cell.

Cytokinensis

The cytoplasm then divides into two forming two daughter cells.

Answer 2

1. In interphase, the cell prepares for division by growing, carrying out its normal functions, and replicating its DNA.
2. During mitosis, the nucleus divides to create two identical daughter cells with the same number of chromosomes as the parent cell.
3. In cytokinesis, the cytoplasm divides, splitting the organelles and other cellular components between the two daughter cells, resulting in the formation of two separate, identical cells.
