Mitosis and Cell Cycle

Mitosis and Cell Cycle definitions

Cell Cycle- The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication that produces two daughter cells.

Mitosis- a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.

Steps of Cell Cycle

G1- cell grows rapidly

G0- the resting stage of the cell.

G2- preperation or division

M (mitosis)- forms 2 nuclei, each containing a seperate set of chromosomes.

C (cytokinesis)- the division of the core of the cytoplasm.

Steps of Mitosis

Prophase- the chromatids coils to form visible chromosomes and neuclear envelops dissolves.

Metaphase- Chromosomes move to the middle. Spindle lengths chromatids to each chromosome and opposite poles.

Anaphase- the center splits. Sister chromatids and pulled apart to opposite poles of the cell.

Telophase- a nuclear envelope forms around each pole. 2 daughter cells proceed and go into the next phase.
