Quick 10Q: 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

What occurs during Anaphase of mitosis?

Back

During Anaphase, microtubules pull sister chromatids apart to opposite poles of the cell.

Front

What is the purpose of the G1 checkpoint?

Back

The G1 checkpoint determines whether the cell should proceed to divide, assessing cell size, nutrients, and DNA integrity.

Front

What happens during Metaphase of mitosis?

Back

During Metaphase, sister chromatids align at the metaphase plate in the middle of the cell.

Front

What is the end result of mitosis?

Back

Mitosis results in 2 identical diploid cells, each with the same number of chromosomes as the original cell.

Front

Define Mitosis.

Back

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

Front

What is the role of microtubules in mitosis?

Back

Microtubules help separate sister chromatids and pull them to opposite poles during Anaphase.

Front

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

Back

The S phase is when DNA replication occurs, resulting in two copies of each chromosome.

Front

What occurs during Prophase of mitosis?

Back

During Prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells contain one set of chromosomes (n), while diploid cells contain two sets (2n).
