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 stages of Mitosis?

Back

The main stages of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

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 is Metaphase?

Back

Metaphase is the stage of Mitosis where chromosomes align at the cell's equatorial plane, preparing for separation.

Front

What is Anaphase?

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite poles of the cell.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes de-condense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is the role of centromeres in Mitosis?

Back

Centromeres are the structures that hold sister chromatids together and are essential for their proper separation during Mitosis.

Front

Why is DNA replication important before Mitosis?

Back

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

Front

What are spindle fibers?

Back

Spindle fibers are protein structures that help separate chromosomes during Mitosis by attaching to centromeres.

Front

What is a chromatid?

Back

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