Cell Cycle

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (which includes G1, S, and G2 phases) and the M phase (mitosis and cytokinesis).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary 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 in the cell cycle?

Back

The G2 phase is a period of further growth and preparation for mitosis, where the cell checks for DNA damage and ensures all DNA is replicated.

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 are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is cytokinesis?

Back

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

Front

Which type of cell divides most frequently?

Back

Skin cells divide most frequently compared to liver, blood, and nerve cells.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms that ensure the cell is ready to proceed to the next phase of the cell cycle, preventing errors.
