Mitosis

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the 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, ensuring each daughter cell will receive an identical set of chromosomes.

Front

What happens during Telophase?

Back

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

Front

What is Interphase?

Back

Interphase is the stage of the cell cycle where the cell spends most of its life, preparing for mitosis by replicating its DNA and organelles.

Front

How many chromosomes do daughter cells have after Mitosis?

Back

Daughter cells have the same number of chromosomes as the parent cell; in the case of fruit flies, they would have 8 chromosomes.

Front

What is the significance of Mitosis?

Back

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

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.
