Cell Cycle and Cancer

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (M).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal functions, preparing for DNA replication.

Front

What is the S phase responsible for?

Back

The S phase is responsible for replicating the cell's DNA, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What occurs during the G2 phase?

Back

During the G2 phase, the cell continues to grow, produces proteins, and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What are checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle, preventing errors in DNA replication and division.

Front

Where are the checkpoints located in the cell cycle?

Back

Checkpoints are located after each phase of the cell cycle: G1, S, and G2.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

What can cause cancer?

Back

Cancer can be caused by errors in the regulatory processes of the cell cycle, leading to uncontrolled cell growth.

Front

How does uncontrolled cell growth relate to cancer?

Back

Uncontrolled cell growth occurs when cells bypass checkpoints and continue to divide without regulation, leading to tumor formation.
