In animal cells,during the $S$ phase,$DNA$ replication begins in the ......... and the centriole duplicates in the cytoplasm.

In which phase does $DNA$ replication occur?

In humans, how many hours does it take to complete one full cell cycle (in $hours$)?

$DNA$ replicates:

The sequence of events by which a cell duplicates its genome,synthesizes the other constituents of the cell and eventually divides into two daughter cells is termed as

Which of the following is true for the $G_0$ phase?
$I.$ It is a quiescent stage.
$II.$ The cell cycle is arrested in this stage.
$III.$ $G_0$ cells do not grow or proliferate,but are metabolically active.
$IV.$ $G_0$ cells divide in response to stimuli.
