Answer;
Sister chromatids may drift apart after being synthesized.
Explanation;
-Cohesin is a protein which localizes between the sister chromatids and holds them together to resist the pull of the kinetochore microtubules.
-Because cohesin enables sister chromatids to remain attached from the time they are synthesized during S phase until the end of metaphase. If cohesin is defective, sister chromatids may separate before they normally would in anaphase, which would lead to daughter cells that have too few or too many chromosomes.
