It plays important role in growth and repair of cells and tissues in multi-cellular organisms.
Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells
It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.
Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.
