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 is the M checkpoint in the cell cycle?

Back

The M checkpoint ensures that all microtubules are properly attached to kinetochores before the cell proceeds with mitosis.

Front

What is the result of mitosis?

Back

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

Front

What occurs before the process of mitosis?

Back

Before mitosis, DNA is replicated during the S phase of the cell cycle.

Front

What happens during anaphase?

Back

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

Front

Define mitosis.

Back

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

Front

What is the role of sister chromatids in mitosis?

Back

Sister chromatids are identical copies of a chromosome that are separated during mitosis to ensure each daughter cell receives the same genetic material.

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, ensuring that each daughter cell will have a complete set of chromosomes.

Front

What is chromatin?

Back

Chromatin is the complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.

Front

What occurs during prophase?

Back

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