Vedclass · Answer

(B) In the cell cycle,the number of chromosomes remains constant during the $G_{1}$ phase,$S$ phase,and $G_{2}$ phase.During the $S$ phase,the amount of $DNA$ doubles,but the number of chromosomes remains the same because the sister chromatids remain attached at the centromere.In mitosis ($M$-phase),the sister chromatids separate,but each chromatid is considered a chromosome,so the chromosome number in the daughter cells remains equal to the parent cell.Therefore,if a cell has $14$ chromosomes at interphase,it will have $14$ chromosomes at $G_{1}$,$14$ chromosomes after the $S$ phase,and $14$ chromosomes after the $M$-phase.

List $I$	List $II$
$A$. $M$ Phase	$I$. Proteins are synthesized
$B$. $G_2$ Phase	$II$. Inactive phase
$C$. Quiescent stage $(G_0)$	$III$. Interval between mitosis and initiation of $DNA$ replication
$D$. $G_1$ Phase	$IV$. Equational division

How many chromosomes will the cell have at $G_{1}$,after $S$ and after $M$-phase respectively,if it has $14$ chromosomes at interphase?
