What is mitosis?

Back

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

What happens during prophase?

Back

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

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.

What occurs during metaphase?

Back

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

What happens during anaphase?

Back

During anaphase, the sister chromatids are pulled apart and move toward opposite poles of the cell.

What occurs 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.

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell is divided into two daughter cells.

What is the difference between haploid and diploid cells?

Back

Haploid cells contain a single set of chromosomes (n), while diploid cells contain two sets of chromosomes (2n).

What is the role of mitosis in multicellular organisms?

Back

Mitosis plays a crucial role in growth, development, and the replacement of damaged or dead cells in multicellular organisms.
