The Cell Cycle

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows, carries out normal functions, and copies organelles.

Front

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

Back

The S phase is where DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What happens during the G2 phase of the cell cycle?

Back

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

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parent cell divides into two daughter cells after mitosis.

Front

What is a checkpoint in the cell cycle?

Back

A checkpoint is a control mechanism that ensures the proper progression of the cell cycle, preventing errors.

Front

What are the main checkpoints in the cell cycle?

Back

The main checkpoints are the G1 checkpoint, G2 checkpoint, and the spindle checkpoint.

Front

What is the G0 phase?

Back

The G0 phase is a resting state where cells exit the cell cycle and do not actively divide.

Front

What is the role of the spindle checkpoint?

Back

The spindle checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before mitosis proceeds.

Front

What is the significance of the G1 checkpoint?

Back

The G1 checkpoint assesses cell size, DNA integrity, and nutrient availability before the cell commits to division.
