Cell Cycle Flashcard 2 (24-25)

Front

What are checkpoint proteins?

Back

Checkpoint proteins are regulatory proteins that ensure a cell does not proceed to the next phase of the cell cycle until certain conditions are met, preventing uncontrolled cell division.

Front

What happens during interphase?

Back

During interphase, a typical cell carries out its normal functions, grows, and prepares for cell division.

Front

Where does most cell division occur in an organism?

Back

Most cell division occurs in parts of an organism where there is the most growth, such as in developing tissues.

Front

Why are there multiple checkpoints in the cell cycle?

Back

Multiple checkpoints are present to prevent a cell from dividing if one of the checkpoints fails, ensuring proper cell division and function.

Front

How does DNA damage relate to cancer?

Back

Damage to DNA can affect the production of checkpoint proteins, leading to uncontrolled cell division and potentially cancer.

Front

What is the role of DNA polymerase in the cell cycle?

Back

DNA polymerase is an enzyme necessary for replicating DNA during the S phase of the cell cycle.

Front

What is the significance of the G1 phase in the cell cycle?

Back

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

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the purpose of the G2 phase?

Back

The G2 phase is the second gap phase where the cell continues to grow and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.
