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 occurs during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and spindle fibers begin to form.

Front

What happens 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.

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes de-condense, nuclear membranes reform around each set of chromosomes, and the cell begins to pinch in preparation for cytokinesis.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is Interphase?

Back

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

Front

Why is DNA replication important before cell division?

Back

DNA replication is crucial before cell division 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 cell division by attaching to the centromeres and pulling them apart.
