Vedclass · Answer

(C) In the cell cycle,the $G_1$ phase is the first gap phase where the cell grows and prepares for $DNA$ replication,but $DNA$ replication (chromosome replication) occurs during the $S$ phase (Synthesis phase).Therefore,Statement $A$ is incorrect.After the $S$ phase,the cell enters the $G_2$ phase,where it prepares for mitosis. After completing the $G_2$ phase,the cell enters the $M$ phase (Mitosis).Therefore,Statement $B$ is correct.Thus,Statement $A$ is incorrect and Statement $B$ is correct.

Column-$I$	Column-$II$
$A$. $G_2$-phase	$1$. First phase of prophase-$I$
$B$. Anaphase	$2$. Proteins are synthesized in preparation for mitosis
$C$. Leptotene	$3$. Terminalisation of chiasmata
$D$. Diakinesis	$4$. Centromeres split and chromatids separate

Column $-I$	Column $-II$
$(a)$ Synapsis aligns homologous chromosomes	$(i)$ Anaphase$-I$
$(b)$ Synthesis of tubulin protein	$(ii)$ Zygotene
$(c)$ Action of enzyme recombinase	$(iii)$ $G_2$-phase
$(d)$ Centromeres split and chromatids move towards opposite poles	$(iv)$ Anaphase$-II$
	$(v)$ Pachytene

Statement $A$ - Chromosomes replicate in the $G_1$ phase.
Statement $B$ - The cell enters mitosis from the $G_2$ phase.
