Cell Division: Mitosis

Front

What is mitosis?

Back

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

Front

What are the stages of mitosis?

Back

The stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

During Prophase, the chromosomes condense and become visible, the nuclear envelope breaks down, and the spindle fibers begin to form.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes line up at the cell's equator and attach to spindle fibers.

Front

What is Anaphase?

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite ends 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 spindle fibers disassemble.

Front

What is cytokinesis?

Back

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

Front

Why is DNA replication important before mitosis?

Back

DNA replication is important to ensure that each daughter cell receives an identical set of genetic information.

Front

What is a chromosome?

Back

A chromosome is a single, long DNA molecule that is tightly coiled and compacted.

Front

How many chromosomes do humans have?

Back

Humans typically have 46 chromosomes, arranged in 23 pairs.
