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.
