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 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.

The sister chromatids will begin the process of separation in about ; ( B )

12 hours

Mitosis is a biological process whereby a parent cell divides into two equal daughter cells containing the same number of chromosomes and nucleus each just like the parent cell. Mitosis in mouse Fibroblast cells have been studied under normal circumstances and documented overtime for reference and research purposes just like in the question above.

From the study of Mitosis in fibroblast cells it takes approximately 12 hours after the growing of cell organelles and synthesization of protein for sister chromatids to be begin its separation process.

Note : If the process of separation by the sister chromatids occurs in lesser hours it is most likely caused by (HDAC) activity inhibition .

Hence we can conclude that The sister chromatids will begin the process of separation in about ; ( B ) 12 hours
