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, essential for growth and repair.

Front

What are the main phases of mitosis?

Back

The main 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 occurs in Metaphase?

Back

In Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is Anaphase?

Back

Anaphase is the phase where sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter 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 a chromosome?

Back

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

Front

What is a chromatid?

Back

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

Front

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.

Front

What is the significance of mitosis?

Back

Mitosis is crucial for growth, tissue repair, and asexual reproduction in organisms.
