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 spindle fibers begin to form.

Front

What occurs 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 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 Cytokinesis?

Back

Cytokinesis is the process that follows Mitosis, where the cytoplasm of the cell 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 growing and replicating its DNA.

Front

How long does a cell typically spend in Interphase?

Back

A cell typically spends about 90% of its life cycle in Interphase.

Front

What role do spindle fibers play in Mitosis?

Back

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