What is cytokinesis?

• This is when two cells merge together to make one giant cell.
• The stage where chromosomes migrate to the opposite ends of the cell. 
• The stage of the cell cycle where the rest of the cell divides after mitosis is complete.
• The stage in which DNA condenses into chromosomes.
