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.
