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 Mitotic phase (M phase).

Front

What occurs 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 happens 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 of the cell cycle?

Back

The G2 phase is the period after DNA synthesis where the cell prepares for mitosis, including further growth and organelle duplication.

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 step of cell division where the cytoplasm divides, resulting in two separate cells.

Front

What is the significance of the G0 phase?

Back

The G0 phase is a resting state where cells are not actively preparing to divide; many differentiated cells, like neurons, enter this phase.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are control mechanisms that ensure the proper progression of the cell cycle, preventing errors such as DNA damage.

Front

What is the difference between haploid and diploid cells?

Back

Diploid cells have two sets of chromosomes (one from each parent), while haploid cells have one set of chromosomes.

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the cell cycle by activating cyclin-dependent kinases (CDKs), which drive the cell through different phases.
