Phases of 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.

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 during Metaphase?

Back

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

Front

What is the significance of Anaphase?

Back

In Anaphase, the centromeres divide, and the sister chromatids (now called chromosomes) are pulled apart to opposite poles of the cell.

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 the purpose of Mitosis?

Back

The purpose of Mitosis is to divide the nucleus, ensuring that each daughter cell receives an identical set of chromosomes.

Front

Define 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.

Front

What is the role of the Spindle Apparatus?

Back

The spindle apparatus is responsible for separating the chromosomes during cell division.
