This pulling is done by microtubules. Place the following events in order as they occur during cell division through mitosis. Once the sister chromatids split during anaphase theyre called sister chromosomes.

This is when the lined up chromosomes begin to pull apart to other sides of the large undivided cell. 5 Where does crossing over occur. Shortening of the polar microtubules B.

In telophase chromosomes arrive at opposite poles and nuclear envelope material surrounds each set of chromosomes. Multiple Choice Book rences O The spindle fibers shorten and the sister chromatids begin to separate and move to opposite ends of the cell.

Disintegration of nuclear membrane The following events occur during the various phases of the cell cycle. The spindle fibers attach to the sister chromatids and align them along the center of the cell. Homologues reach their respective poles during telophase I the nuclear membrane re-forms to produce two separate nuclei.
