Definitions:

S Phase

The phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.

Cytokinesis

Cytokinesis is the process during cell division in which the cytoplasm of a single eukaryotic cell is divided into two daughter cells.

G₁ Phase

The first of four phases of the cell cycle in which the cell grows in size and synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.

G₂ Phase

A phase of the cell cycle following DNA synthesis (S phase) and preceding mitosis (M phase), during which cells prepare for division and undergo growth and protein synthesis.
