What is Mitosis?

Back

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

What is a Chromosome?

Back

A chromosome is a structure made of DNA and proteins that contains genetic information. It is visible during cell division.

What is a Chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

What happens during Prophase in Mitosis?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

What occurs during Metaphase in Mitosis?

Back

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

What is Anaphase in Mitosis?

Back

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

What happens during Telophase in Mitosis?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

What is Cytokinesis?

Back

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