Vedclass · Answer

(C) Endomitosis is a process where the chromosomes replicate without the division of the nucleus $(karyokinesis)$ or the cytoplasm $(cytokinesis)$.This results in polyploidy,where the cell contains multiple sets of chromosomes.Since the nuclear envelope does not break down and the cell does not divide,the statement in the Reason $(R)$ that 'mitosis occurs within the nucleus' is factually incorrect as true mitosis involves the breakdown of the nuclear envelope and subsequent division of the nucleus.Therefore,the Assertion $(A)$ is correct,but the Reason $(R)$ is incorrect.

List-$I$	List-$II$
$(a)$ $S$ phase	$(i)$ Proteins are synthesized
$(b)$ $G_2$ phase	$(ii)$ Inactive phase
$(c)$ Quiescent stage	$(iii)$ Interval between mitosis and initiation of $DNA$ replication
$(d)$ $G_1$ phase	$(iv)$ $DNA$ replication

$A$ : Endomitosis does not cause karyokinesis or cytokinesis.
$R$ : In endomitosis,mitosis occurs within the nucleus.
