cell cycle

Interphase

95% of the cell life.

Mitosis

Cell division

Prophase

Nuclear membrane breaks down. Chromatin turns into chromosomes. Nucleolus disappears and spindles appear

Metaphase

Chromosomes cluster and become aligned at the center of the spindle midway between the centrioles so that a straight line of chromsomes seen.

Anaphase

The centromeres that have held the chromatids together split and the chromatids (now called chromosomes again) beigin to move slowly apart toward opposite ends of the cell.

Telophase

Chromosomes at opposite ends of the cell uncoil to become threadlike chromatin again. The spindle breaks down and disappears, a nuclear envelope forms around each chromatin mass and nucleoli appear in

Cytokinesis

When the cell splits into two cells.
