A researcher is observing the separation of sister chromatids during the process of mitosis in mouse fibroblast cells. If the researcher observes a cell that has just finished growing organelles and synthesizing proteins, but has not started to replicate its chromosomes, in about how many hours will sister chromatids begin the process of separation?

A. 21 hours

B. 12 hours

C. 10 hours

D. 9 hours

The correct answer is option B. "12 hours".

Explanation:

The process of mitosis in mouse fibroblast cells have been studied and characterized for researches purposes. Therefore, it is possible to predict that it will take around 12 hours for mouse fibroblast cells to begin the process of sister chromatids separation after finishing growing its organelles and synthesizing proteins. If the process takes less time than 12 hours will indicate a premature sister chromatid separation, and that something has caused down regulation or inhibition the histonedeacetylase (HDAC) activity.
