Mitosis: The Dance of Sister Chromatids

What happens in Anaphase?

A. Sister chromatids separate and move toward opposite poles.

B. Chromosomes line up single file down the middle of the cell.

C. Nuclei re-form.

D. The nucleus disintegrates.

Answer:

In Anaphase, sister chromatids separate and move toward opposite poles.

Explanation: In Anaphase, sister chromatids separate and move toward opposite poles. This is the stage of mitosis when the duplicated chromosomes are pulled apart by the spindle fibers. As the sister chromatids are separated, they become individual chromosomes.

So, in this phase of mitosis, the sister chromatids do their own little dance as they migrate to opposite poles of the cell, ready to form new nuclei in the newly forming daughter cells.

Understanding the intricacies of mitosis and each phase it entails is crucial in comprehending how cells divide and replicate. It's a fascinating process that showcases the complexity and precision of cellular division.
