$A$ cell has $32$ chromosomes. It undergoes mitotic division. What will be the chromosome number $(n)$ during metaphase? What would be the $DNA$ content $(c)$ during anaphase?

(A) $\Rightarrow$ In mitosis,the number of chromosomes remains constant throughout the process. Therefore,during metaphase,the chromosome number remains $32$.
$\Rightarrow$ During the $S$ phase of interphase,the $DNA$ content doubles. If the initial $DNA$ content is $2c$,it becomes $4c$ after replication. During anaphase,the sister chromatids separate,but the total $DNA$ content of the cell remains $4c$ until cytokinesis is completed.
