Synthesis of mitotic spindle microtubules

Vedclass · Answer

(C) The $S$ phase (Synthesis phase) of the cell cycle is primarily characterized by $DNA$ replication and the synthesis of histone proteins. During this phase,the amount of $DNA$ per cell doubles,but the chromosome number remains the same. Option $A$ ($DNA$ replication) and Option $B$ (doubling of genetic material) occur during the $S$ phase. Option $C$ (synthesis of mitotic spindle microtubules) occurs during the $G_2$ phase. Option $D$ (separation of sister chromatids) occurs during the Anaphase stage of Mitosis ($M$ phase). Therefore,both $C$ and $D$ are not associated with the $S$ phase. However,in the context of typical multiple-choice questions regarding cell cycle events,the formation of spindle fibers is a distinct event of the $G_2$ phase,while chromatid separation is a hallmark of the $M$ phase.

Which of the following processes is not associated with the $S$ phase of the cell cycle?
