Question

During cell cycle, cell enters the interphase before it undergoes another cycle of division. Why?

Answer 1

$\bullet$ The cell cycle consists of two phases.

$\bullet$ $1.$ Interphase. Also known as the resting phase of the cell cycle; interphase is the time during which the cell prepares for division by undergoing both cell growth and $DNA$ replication. It includes the following stages:

$G_1$ phase $\left(\text{First growth phase}\right).$

$S$ phase $\left(\text{Synthesis phase}\right).$

$G_2$­ phase $\left(\text{Second growth phase}\right).$

$\bullet$ $2.M$ Phase $\left(\text{Mitotic phase}\right).$ It occurs in two steps: karyokinesis $\left(\text{nuclear division}\right)$ and cytokinesis $\left(\text{cytoplasm division}\right).$
