What is mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring that each new cell receives an exact copy of the parent cell's DNA.

What happens during Prophase?

Back

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

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.

What is Anaphase?

Back

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

What happens during Telophase?

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 back into chromatin.

What is cytokinesis?

Back

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

What is the role of spindle fibers in mitosis?

Back

Spindle fibers are responsible for separating the chromosomes during mitosis, ensuring that each daughter cell receives the correct number of chromosomes.

Define chromatid.

Back

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

Front

What is a centromere?

Back

A centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during mitosis.
