AP Bio Topic 4.7 Cell Cycle Regulation

Front

How is the cell cycle regulated?

Back

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

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 S phase in the cell cycle?

Back

The S phase is where DNA replication occurs.

Front

What are cyclin-dependent kinases (CDKs)?

Back

CDKs are enzymes that regulate the cell cycle.

Front

What are cell cycle checkpoints?

Back

Control mechanisms that ensure the integrity of the cell cycle.

Front

What is the G1 phase of the cell cycle?

Back

The G1 phase is the first gap phase where the cell grows and prepares for DNA synthesis.

Front

What happens during the G2 phase of the cell cycle?

Back

The G2 phase is the second gap phase where the cell prepares for mitosis.

Front

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

Back

The M phase is where mitosis occurs, leading to cell division.

Front

What role do growth factors play in the cell cycle?

Back

Growth factors are external signals that promote cell division and growth.

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 not properly regulated.
