Vedclass · Answer

(A) During the prophase stage of mitosis,the $DNA$ has already replicated during the $S$-phase of interphase.Each chromosome consists of two sister chromatids held together at a single centromere.Each chromatid has its own kinetochore,which is a protein structure on the centromere where spindle fibers attach.Therefore,for a single chromosome in prophase: - Number of centromeres = $1$- Number of chromatids = $2$- Number of kinetochores = $2$Thus,the correct sequence is $1, 2, 2$.

Select the correct option for a chromosome in prophase,representing the number of centromeres,chromatids,and kinetochores respectively.
