Vedclass · Answer

(A) $S$ or synthetic phase is the period during which $DNA$ synthesis or replication takes place. Thus,$I$ is correct.Zygotene is the second stage of prophase-$I$,where homologous chromosomes pair together,a process known as synapsis. Thus,$II$ is correct.Crossing over occurs during the pachytene stage of prophase-$I$,not diplotene. Thus,$III$ is incorrect.Meiosis occurs only in diploid cells,not haploid cells. Thus,$IV$ is incorrect.$G_{0}$ phase (quiescent stage) is the inactive stage,not $G_{2}$-phase. Thus,$V$ is incorrect.Therefore,only $I$ and $II$ are correctly matched.

Select the matched ones.
$I.$ $S$-phase - $DNA$ replication
$II.$ Zygotene - Synapsis
$III.$ Diplotene - Crossing over
$IV.$ Meiosis - Shown by haploid and diploid cells
$V.$ $G_{2}$-phase - Quiescent stage
