AP Biology Cell Cycle Review

Front

What happens if DNA damage is detected at the G2 checkpoint?

Back

The cell cycle stops until the DNA can be repaired or undergoes apoptosis.

Front

What is the role of cyclins and cyclin-dependent kinases (CDKs) in the cell cycle?

Back

To control the cell cycle through checkpoints.

Front

What triggers the cell to pass the G1 checkpoint and divide?

Back

Presence of growth factors.

Front

Which checkpoint is considered the most important in mammalian cells?

Back

G1 checkpoint.

Front

What is the function of tumor suppressor genes?

Back

To inhibit the cell cycle and promote apoptosis.

Front

Define the cell cycle.

Back

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

Front

What are the main phases of the cell cycle?

Back

G1, S, G2, and M phases.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two sister chromatids for each chromosome.

Front

What is apoptosis?

Back

A programmed cell death process that eliminates damaged or unnecessary cells.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints ensure that the cell is ready to proceed to the next phase, preventing errors.
