What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers are structures that pull chromosomes apart during anaphase, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

During telophase, the chromosomes de-condense back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the G1 checkpoint?

Back

The G1 checkpoint is a control mechanism that ensures the cell is ready to enter the S phase and begin DNA replication.

Front

What is the G2 checkpoint?

Back

The G2 checkpoint verifies that DNA has been completely and accurately replicated before the cell enters mitosis.
