Mitosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are chromosomes?

Back

Chromosomes are long, thread-like structures made of DNA and proteins that contain genetic information.

Front

What is a sister chromatid?

Back

A sister chromatid is one of the two identical halves of a duplicated chromosome, joined together at the centromere.

Front

What is a centromere?

Back

A centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

What are the phases of mitosis?

Back

The phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What happens during prophase?

Back

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

Front

What happens during metaphase?

Back

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

Front

What happens during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

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

Front

What is cytokinesis?

Back

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