What is meant by cell cycle? Explain.

(N/A) $\Rightarrow$ Cell division is a very important process in all living organisms.
$\Rightarrow$ $DNA$ replication and cell growth take place during cell division.
$\Rightarrow$ All processes like cell division,$DNA$ replication,and cell growth must occur in a coordinated manner to ensure correct division and the formation of progeny cells containing intact genomes.
$\Rightarrow$ Cell Cycle: 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 the cell cycle.
$\Rightarrow$ Although cell growth (in terms of cytoplasmic increase) is a continuous process,$DNA$ synthesis occurs only during one specific stage in the cell cycle.
$\Rightarrow$ The replicated chromosomes $(2n)$ $(DNA)$ are then distributed to daughter nuclei by a complex series of events during cell division.
$\Rightarrow$ These events are under genetic control.
