Cell Communication & Cell Cycle review

Front

What is the G2 checkpoint in the cell cycle?

Back

The G2 checkpoint verifies that DNA has been replicated correctly and checks for any DNA damage before the cell enters mitosis.

Front

What phases are included in interphase?

Back

Interphase consists of three phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

Which phase of the cell cycle does not involve cell growth?

Back

M phase (Mitosis) is the phase where the cell divides, and it does not involve growth.

Front

True or False: The cell grows through all three phases of interphase.

Back

True.

Front

What are proto-oncogenes?

Back

Proto-oncogenes are normal genes that can become oncogenes due to mutations, leading to cancer.

Front

True or False: Proto-oncogenes can mutate into oncogenes.

Back

True.

Front

What occurs after mitosis in the cell cycle?

Back

Cytokinesis occurs after mitosis, resulting in the division of the cytoplasm and formation of two daughter cells.

Front

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

Back

The S phase is where DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints ensure that the cell cycle progresses only when certain conditions are met, preventing errors such as DNA damage.

Front

What happens during G1 phase of the cell cycle?

Back

During G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.
