What happens during prophase?

Back

During prophase, chromatin condenses into chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

What occurs during metaphase?

Back

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

What is anaphase?

Back

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

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.

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Why is DNA replication important before mitosis?

Back

DNA replication is important before mitosis to ensure that each daughter cell receives an identical set of genetic information.

Front

What are chromosomes?

Back

Chromosomes are structures made of DNA and protein that contain genetic information; they become visible during cell division.

Front

What is the role of the mitotic spindle?

Back

The mitotic spindle is a structure made of microtubules that helps separate chromosomes during mitosis.
