Mitosis

Front

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.

Front

What occurs during interphase?

Back

During interphase, the cell grows, DNA is replicated, and the cell prepares for mitosis. DNA does not condense during this phase.

Front

What is a chromatid?

Back

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

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 centromere?

Back

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

Front

What happens during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin 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 of the chromosomes.

Front

What happens during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring each new cell will receive an identical set of chromosomes.

Front

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.

Front

What is cytokinesis?

Back

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