Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death.

Front

What are internal and external regulators of the cell cycle?

Back

Internal and external regulators are proteins that control the progression of the cell cycle.

Front

What is metastasis?

Back

Metastasis is the spreading of cancerous cells to other parts of the body.

Front

Which of the following is NOT a normal reason for apoptosis?

Back

Encourage division of cancer cells.

Front

What is the function of cyclins?

Back

Cyclins are proteins that regulate when and how often a cell divides.

Front

Define the cell cycle.

Back

The cell cycle is the series of events that take place in a cell leading to its division and replication.

Front

What role do checkpoints play in the cell cycle?

Back

Checkpoints are control mechanisms that ensure the proper progression of the cell cycle.

Front

What is the significance of DNA repair mechanisms?

Back

DNA repair mechanisms correct errors in DNA to prevent mutations and maintain genomic stability.

Front

What is carcinogenesis?

Back

Carcinogenesis is the process by which normal cells are transformed into cancer cells.

Front

What is the role of tumor suppressor genes?

Back

Tumor suppressor genes help regulate cell division and prevent uncontrolled growth.
