Flashcards

Cell Division

The division of a cell into two genetically identical daughter cells.

DNA Replication

The process of copying DNA to create two identical copies. It occurs during the S phase of interphase.

Mitosis

The stage of the cell cycle where the nucleus divides, forming two identical nuclei. Consists of four phases: prophase, metaphase, anaphase, and telophase.

Interphase

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