Cell Cycle Flashcard 2 (24-25)

Front

What is the purpose of checkpoints in the cell cycle?

Back

To prevent a cell from dividing if one of the checkpoints fails.

Front

Where does the most cell division occur in a living organism?

Back

In parts of an organism where there is the most growth.

Front

How can damage to DNA lead to cancer?

Back

Damage to DNA can affect the production of checkpoint proteins.

Front

What happens during interphase in a typical cell?

Back

The cell carries out its normal functions.

Front

How do cells control their growth and division?

Back

Checkpoint proteins stop a cell from dividing until it is ready.

Front

What is interphase?

Back

The phase of the cell cycle where the cell prepares for division and carries out its normal functions.

Front

What are checkpoint proteins?

Back

Proteins that monitor the cell cycle and prevent progression until certain conditions are met.

Front

What is the significance of the G1 checkpoint?

Back

It checks for cell size, nutrients, and DNA integrity before the cell enters the S phase.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two copies of each chromosome.

Front

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

Back

The M phase is where mitosis and cytokinesis occur, leading to cell division.
