Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and the mitotic phase (M).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows, synthesizes proteins, 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 G2 phase responsible for?

Back

The G2 phase is responsible for further cell growth, protein synthesis, and preparation 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.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate cells.

Front

What is the M phase of the cell cycle?

Back

The M phase includes both mitosis and cytokinesis, where the cell divides into two daughter cells.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the cell cycle progresses correctly and prevents errors in cell division.

Front

What is the significance of the G1 checkpoint?

Back

The G1 checkpoint assesses whether the cell is ready to enter the S phase, checking for DNA damage and sufficient resources.

Front

What happens if a cell does not pass the G1 checkpoint?

Back

If a cell does not pass the G1 checkpoint, it may enter a resting state called G0 or undergo apoptosis (programmed cell death).
