Cell Cycle

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are G1 phase, S phase, G2 phase, and M phase.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal metabolic processes.

Front

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

Back

The S phase is significant because it is when DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What happens during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell prepares for mitosis by producing proteins and organelles needed for cell division.

Front

What is the M phase of the cell cycle?

Back

The M phase is the phase of the cell cycle where mitosis occurs, leading to cell division.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints in the cell cycle monitor and regulate the progression of the cell cycle, ensuring that each phase is completed accurately before moving to the next.

Front

What is the purpose of the cell cycle?

Back

The purpose of the cell cycle is to ensure proper cell growth, DNA replication, and division, allowing for tissue growth and repair.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the division of the cytoplasm, resulting in two separate daughter cells.

Front

What are cyclins and their role 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.
