Cell Cycle Regulation

Apoptosis is a form of programmed cell death that occurs in a regulated manner, typically triggered by normal physiological processes.

Necrosis is a form of uncontrolled cell death resulting from acute cellular injury, leading to inflammation and damage to surrounding tissues.

Cell cycle checkpoints are control mechanisms that ensure the integrity of the cell cycle, preventing the progression of the cycle if errors are detected.

The M checkpoint ensures that all chromosomes are properly attached to the mitotic spindle before the cell enters anaphase.

The G2 phase is the stage in the cell cycle where the cell prepares for mitosis, ensuring all DNA is replicated and the cell is ready to divide.

Tumor suppressor genes help regulate cell division and prevent uncontrolled cell growth, acting as a safeguard against cancer.

Mutations in tumor suppressor genes can lead to uncontrolled cell division, contributing to the development of cancer.

The S phase is the part of the cell cycle where DNA replication occurs, resulting in two identical sets of chromosomes.

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

The G0 phase is a resting state where cells exit the cell cycle and cease to divide, often in response to unfavorable conditions.
