Chapter 17: The Cell Cycle

Cell Cycle

A highly regulated process that ensures proper cell growth, DNA replication, and cell division, leading to the production of two daughter cells with identical genetic material.

Interphase

The longest phase of the cell cycle, where the cell grows, carries out its normal functions, and replicates its DNA.

Mitotic Phase

The shortest phase of the cell cycle, involving the actual division of the cell into two daughter cells.

Cytokinesis

The final stage of the cell cycle, where the cytoplasm divides, and two daughter cells are formed.

Cell-Cycle Control System

A complex network of molecular checkpoints and regulatory mechanisms that ensure the orderly progression of the cell cycle.

Meiosis

A specialized form of cell division that occurs in sexually reproducing organisms, resulting in the production of gametes.

Meiosis I

The first division of meiosis, involving the pairing and separation of homologous chromosomes.

Meiosis II

The second division of meiosis, similar to a mitotic division, involving the separation of sister chromatids.
