Cell Cycle Regulation

Front

What is apoptosis?

Back

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

Front

What is necrosis?

Back

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

Front

What are cell cycle checkpoints?

Back

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

Front

What is the M checkpoint?

Back

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

Front

What is the G2 phase?

Back

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.

Front

What is the role of tumor suppressor genes?

Back

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

Front

How do mutations in tumor suppressor genes affect cancer development?

Back

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

Front

What is the S phase of the cell cycle?

Back

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

Front

What happens during the G1 phase?

Back

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

Front

What is the significance of the G0 phase?

Back

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