Cell Cycle

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication. In cells without a nucleus.

Mitosis is the process by which a cell, which has previously replicated each of its chromosomes, separates the chromosomes in its cell nucleus into two identical sets of chromosomes, each set in its own new nucleus.

A. mitosis

B. cloning

C. sexual reproduction

Meiosis is a special type of cell division necessary for sexual reproduction in eukaryotes, such as animals, plants and fungi. The number of sets of chromosomes in the cell undergoing meiosis is reduced to half the original number, typically from two sets to one set.
