Cell Cycle and Mitosis

Front

What is the G2 checkpoint in the cell cycle?

Back

The G2 checkpoint ensures that all DNA has been replicated correctly and that there are no errors before the cell enters mitosis.

Front

How many chromosomes do fruit fly daughter cells have after mitosis if they originally have 8 chromosomes?

Back

Fruit fly daughter cells have 8 chromosomes after mitosis.

Front

What is the function of the centromere in cell division?

Back

The centromere is the structure that holds sister chromatids together during cell division.

Front

List the stages of the cell cycle in order.

Back

The stages of the cell cycle in order are G1, S, G2, and M.

Front

What is a carcinogen?

Back

A carcinogen is any substance that is known to cause cancer.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the role of mitosis in the cell cycle?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What happens at the G1 checkpoint?

Back

At the G1 checkpoint, the cell assesses its size, nutrients, and DNA integrity before proceeding to DNA synthesis.

Front

Define apoptosis in the context of the cell cycle.

Back

Apoptosis is the process of programmed cell death that eliminates damaged or unnecessary cells.

Front

What is the significance of the M checkpoint?

Back

The M checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before the cell divides.
