cancer

A condition of unregulated cell division, often resulting in the development of tumors and disease.

cyclins

A family of several different proteins that are produced in different amounts during different phases of the cell cycle so that they can bind to and regulate cyclin dependent kinases, thus cueing the progression of the cell cycle.

cyclin-dependent kinase (CDK)

An enzyme that is activated by binding to the appropriate cyclin partner, gaining the ability to transfer a phosphate group to a target protein.

checkpoint

A point of transition between one phase of the cell cycle and the next phase of the cell cycle.

DNA replication

The process of duplicating a DNA molecule, during
which the parental strands separate and new partner strands are made.

apoptosis
