Cell Cycle and Cancer

Front

What are the checkpoints in the cell cycle?

Back

Checkpoints are regulatory points in the cell cycle that ensure proper division and function. They occur after each phase: G1, S, G2, and before M phase.

Front

What is the G1 phase of the cell cycle?

Back

The G1 phase is the first stage of interphase where the cell grows, doubles its organelles, and carries out normal functions.

Front

What is the last stage of the cell cycle?

Back

The last stage of the cell cycle is Cytokinesis, where the cell divides into two daughter cells.

Front

What regulates the cell cycle?

Back

The cell cycle is regulated by proteins known as cyclins and cyclin-dependent kinases (CDKs) that control the progression through the phases.

Front

What is the function of the M phase?

Back

The M phase, or mitotic phase, is responsible for cell division, where the cell separates its duplicated chromosomes into two new nuclei.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is the role of proteins in the cell cycle?

Back

Proteins play a crucial role in regulating the cell cycle by acting as checkpoints and ensuring that the cell is ready to proceed to the next phase.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.

Front

What occurs during G2 phase?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis, ensuring all DNA is replicated and undamaged.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints are significant as they prevent the cell from progressing to the next phase until certain conditions are met, ensuring proper cell division.
