Vedclass · Answer

(D) During the process of mitosis, the $Prophase$ stage is characterized by the initiation of condensation of chromosomal material. As the cell progresses into $late prophase$, the nuclear envelope, nucleolus, Golgi complex, and endoplasmic reticulum $(ER)$ begin to disappear. These structures completely disintegrate by the end of $prophase$ to allow the spindle fibers to attach to the kinetochores of the chromosomes.

Column-$I$	Column-$II$
$1$. Metaphase	$p$. Chromosomal material condensed
$2$. Prophase	$q$. Nucleolus reform
$3$. Anaphase	$r$. Spindle fibre attach to kinetochores
$4$. Telophase	$s$. Chromatids move to opposite poles

During mitosis, the $ER$ and nucleolus begin to disappear at:
