Mitosis

Front

What is Mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the original cell.

Front

What are the main stages of Mitosis?

Back

The main stages of Mitosis are Prophase, Metaphase, Anaphase, and Telophase, often abbreviated as PMAT.

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 happens during Metaphase?

Back

During Metaphase, the chromosomes line up in the middle of the cell, and spindle fibers attach to the centromeres of the chromosomes.

Front

What happens during Anaphase?

Back

During Anaphase, the sister chromatids are pulled apart and move towards 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 final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is a Chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What is a Centromere?

Back

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

Front

What is a Sister Chromatid?

Back

A sister chromatid is one half of a duplicated chromosome, which is joined to its identical twin at the centromere.
