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.

$ii$. $S$ phase	$Q$. Karyokinesis and cytokinesis
$iii$. $G_2$ phase	$R$. $1^{st}$ phase of interphase
$iv$. $M$ phase	$S$. Synthesis of $DNA$

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