Answer:
Anaphase
Explanation:
After anaphase, a cleavage furrow forms in the equatorial cortex in typical animal mitosis. To divide the two daughter cells, this furrow then progresses inwards.
The sister chromatids differentiate from each other in anaphase and are pulled toward opposite ends of the cell. The "glue" of protein that binds together the sister chromatids is broken down, causing them to separate. Each one now has a chromosome of its own.
