Match the following:

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

Identify the correct statements:
Statement $X$: Mitosis occurs in somatic cells and meiosis occurs in reproductive cells.
Statement $Y$: During mitosis,$DNA$ synthesis occurs once for one cell division,and in meiosis,$DNA$ synthesis occurs twice for two cell divisions.
Statement $Z$: Mitosis and meiosis occur in organisms that reproduce both sexually and asexually.

Which of the following is true for a syncytium?

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

Select the correct statements.
$A$. Tetrad formation is seen during Leptotene.
$B$. During Anaphase,the centromeres split and chromatids separate.
$C$. Terminalization takes place during Pachytene.
$D$. Nucleolus,Golgi complex and $ER$ are reformed during Telophase.
$E$. Crossing over takes place between sister chromatids of homologous chromosomes.
Choose the correct answer from the options given below:

Select the correct match for $X$ and $Y$:
