_ – Chromosomes line up in the center of the cell.

_ – Two new nuclear membranes form around the separated chromosomes.

_ – Sister chromatids are pulled apart to opposite ends of the cell.

Mistakes in mitosis, called _, can occur during the copying process.

The _ gene acts as a set of instructions for regulating cell growth.
