Vedclass · Answer

(D) Statement $(1)$ is correct: Synapsis,the pairing of homologous chromosomes,occurs during the zygotene stage of prophase $I$ in meiosis.Statement $(2)$ is incorrect: In meiosis $I$,homologous chromosomes separate,but the centromeres do not split. Centromeres split during anaphase $II$ of meiosis or anaphase of mitosis.Statement $(3)$ is correct: During telophase of mitosis,the chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements. The nuclear envelope assembles around each chromosome cluster,and nucleolus,Golgi complex,and $ER$ reform. Spindle fibers disappear.Statement $(4)$ is correct: During telophase $I$ of meiosis,the nuclear membrane and nucleolus reappear,although the chromosomes may remain partially condensed.

Column $I$	Column $II$
$A$. Synapsis aligns homologous chromosomes	$(i)$ Anaphase $II$
$B$. Synthesis of $RNA$ and protein	$(ii)$ Zygotene
$C$. Action of enzyme recombinase	$(iii)$ $G_2$ phase
$D$. Centromeres do not separate but chromatids move towards opposite poles	$(iv)$ Anaphase $I$
	$(v)$ Pachytene
