Solution:
The sequence of events by which a cell duplicates its genome, synthesises the other constituents of the cell and eventually divides into two daughter cells is termed cell cycle.
There are two main phases of cell cycle:
- Interphase is the phase between subsequent cell divisions is called the interphase
The interphase lasts for more than $95\%$ of the cell cycle
- Division phase is the phase in which the cell actually divides either by mitosis or meiosis
The M phase lasts for less than $5\%$ of the cell cycle
The Interphase is further divided into three phases, which are as follows:
- G1 phase (Gap $-1$ ): During this phase, the cell is metabolically active and continuously grows
- S phase (Synthesis): During this phase, $DNA$ replication takes place. The amount of $DNA$ becomes double during this phase, but the number of chromosomes remain the same.
- G2 phase (Gap $-2$ ): During this phase, protein synthesis takes place.
