Definitions:

G2 Phase

The phase of the cell cycle following DNA synthesis and preceding cell division, during which the cell prepares to divide.

Cell Cycle

The series of events that take place in a cell leading to its division and duplication, including interphase, mitosis, and cytokinesis.

Mitosis

A cellular division process whereby two progeny cells are formed, each carrying the same amount and variety of chromosomes as the parental nucleus, commonly seen in regular tissue growth.

Spindle Poles

The ends of a spindle apparatus, which play a critical role in pulling apart chromosomes during cell division.
