What is the G2 phase of the cell cycle?

Back

The G2 phase is the second gap phase in the cell cycle where the cell prepares for mitosis by producing proteins and organelles.

Front

What occurs during the S phase of the cell cycle?

Back

The S phase is the synthesis phase where DNA replication occurs, resulting in two copies of each chromosome.

Front

How is cancer related to the cell cycle?

Back

Cancer is characterized by unregulated cell division, where cells grow and divide much quicker than they normally would.

What happens when the cell cycle is disrupted?

Back

Disruption of the cell cycle can lead to cancer, as cancer cells undergo uncontrolled division due to mutations in their genes.

What is cytokinesis?

Back

Cytokinesis is the final phase of the cell cycle where the cytoplasm divides, resulting in two daughter cells.

What role do checkpoints play in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle and prevent errors.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that eliminates damaged or unnecessary cells.

Front

What is the significance of DNA replication?

Back

DNA replication is crucial for cell division, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors are non-cancerous growths that do not spread, while malignant tumors are cancerous and can invade nearby tissues.

Front

What are oncogenes?

Back

Oncogenes are mutated genes that have the potential to cause cancer by promoting uncontrolled cell division.
