Definitions:

Cell Cycle

A series of events that take place in a cell leading to its division and duplication, consisting of interphase (G1, S, G2) and mitotic phase.

Cytoplasmic Division

The process, also known as cytokinesis, during which the cytoplasm of a parental cell divides to form two daughter cells.

Nuclear Division

The process by which a nucleus divides, resulting in the segregation of the genome to two daughter nuclei. This occurs via mitosis or meiosis.

Proto-oncogenes

Normal genes that can become oncogenes if mutated or expressed at high levels, potentially leading to cancer.
