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 Anaphase?

Back

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

Front

What happens during Telophase?

Back

During Telophase, the chromosomes reach the poles, begin to de-condense, and the nuclear envelope re-forms around each set of chromosomes.

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for mitosis, including DNA replication.

Front

Why is DNA doubled before Mitosis?

Back

DNA is doubled before Mitosis to ensure that each daughter cell receives an identical set of chromosomes.

Front

What is the role of spindle fibers in Mitosis?

Back

Spindle fibers help separate the chromosomes during Mitosis by attaching to the centromeres and pulling them apart.

Front

What is the significance of Mitosis?

Back

Mitosis is essential for growth, development, and tissue repair in multicellular organisms.
