Cell Cycle Regulation

Front

What are cyclin-dependent kinases (CDKs)?

Back

CDKs are enzymes that regulate the cell cycle.

Front

What are tumor suppressor genes?

Back

Tumor suppressor genes are genes that help regulate cell division and prevent the formation of tumors.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase is where the cell prepares for mitosis.

Front

How is the cell cycle regulated?

Back

The cell cycle is regulated by a complex network of proteins and checkpoints.

Front

What are cell cycle checkpoints?

Back

Control mechanisms that ensure the integrity of the cell cycle.

Front

What is the function of cyclins in the cell cycle?

Back

Cyclins are proteins that activate CDKs and regulate the progression of the cell cycle.

Front

What happens during the S phase of the cell cycle?

Back

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

Front

What is the significance of the M phase in the cell cycle?

Back

The M phase is where mitosis occurs, leading to the division of the cell into two daughter cells.

Front

What role do proto-oncogenes play in the cell cycle?

Back

Proto-oncogenes are genes that promote cell division and can lead to cancer if mutated.

Front

What is apoptosis and how is it related to the cell cycle?

Back

Apoptosis is programmed cell death that can occur if the cell cycle is improperly regulated.
