$b.$ Movement of centriole towards opposite poles
$c.$ Chromosome align on equator
$d.$ Reformation of nuclear membrane and nucleolus

Match the following columns correctly:

Column $I$	Column $II$
$(a)$ $G_1$ phase	$(p)$ Synthesis of new $DNA$ occurs
$(b)$ $G_2$ phase	$(q)$ No $DNA$ synthesis occurs
$(c)$ $S$ phase	$(r)$ $DNA$ synthesis stops
$(d)$ Prophase	$(s)$ Formation of mitotic spindle occurs

Select the incorrect statement from the following.

Match the following columns:

$I$. Interkinesis	$A$. Synapsis
$II$. Interphase	$B$. Formation of bipolar spindle
$III$. Zygotene	$C$. $DNA$ replication
$IV$. Diakinesis	$D$. Stage between two meiotic divisions

$A$ somatic cell that has just completed the $S$ phase of its cell cycle,as compared to a gamete of the same species,has:
