E)Sister chromatids would never separate.

Question

Quizplus · Accepted Answer

Shugoshin protein is responsible for protecting the cohesion protein that holds the sister chromatids together until the proper time of separation at the onset of anaphase II. If breakdown of the shugoshin protein were premature, the cohesion protein would prematurely lose its protective mechanisms, leading to an early separation of sister chromatids. Therefore, the correct answer is C, the separation of sister chromatids would occur prematurely.
