Cell Cycle

Interphase contains 4 stages: G1, S, G2, and mitosis. G1 is the resting stage. Its when the cell grows and mature. S is when DNA is copied. G2 is when the cell prepares for division.
Mitosis is a nuclear division plus cytokinesis and produces two identical daughter cells and the number of chromosomes remain the same.>




Prophase is when the chromatin condenses into chromosomes.

Metaphase is when chromosomes line up across the middle of the cell.

Anaphase is when the sister chromatids separate into individual chromosomes and move apart.

Telophase is when the chromosomes gather at the opposite end of the cell.

Cytokinesis is when the cell membrane pinches the cytoplasm in half.
