Cell Cycle

Front

What happens to the new cells after mitosis is complete?

Back

The new cells are all identical.

Front

In which stage of the cell cycle does the cell grow in size?

Back

G1 phase.

Front

What is the purpose of the M Checkpoint in the cell cycle?

Back

The M Checkpoint ensures that the DNA chromosomes are lined up at the center of the cell and attached to the spindle fibers during mitosis.

Front

During which phase of the cell cycle does the cell make centrioles for mitosis?

Back

G2 phase.

Front

What are the three checkpoints of the cell cycle?

Back

G1 checkpoint, G2 checkpoint, and mitosis/metaphase checkpoint.

Front

What is the main purpose of the G1 checkpoint?

Back

The G1 checkpoint checks for cell size, nutrients, growth factors, and DNA damage before the cell enters the S phase.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the role of the G2 checkpoint?

Back

The G2 checkpoint ensures that DNA has been replicated correctly and checks for DNA damage before the cell enters mitosis.

Front

What is the significance of the metaphase checkpoint?

Back

The metaphase checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before proceeding with anaphase.

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 (mitosis).
