Mitosis

Front

What is Mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring equal distribution of genetic material.

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 by the spindle fibers.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes reach the poles, decondense back into chromatin, and the nuclear envelope re-forms around each set of chromosomes.

Front

What is the role of the spindle apparatus in Mitosis?

Back

The spindle apparatus helps separate the chromosomes during Mitosis by attaching to the centromeres and pulling the sister chromatids apart.

Front

Define 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, development, and tissue repair in multicellular organisms, as it produces new cells.

Front

What is the difference between Mitosis and Cytokinesis?

Back

Mitosis is the division of the nucleus, while Cytokinesis is the division of the cytoplasm, resulting in two separate cells.
