Mitosis Review

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two 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 spindle fibers begin to form.

Front

What occurs in metaphase?

Back

In metaphase, chromosomes line up 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 by spindle fibers and move toward 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 are spindle fibers?

Back

Spindle fibers are threadlike structures that help separate the chromosomes during mitosis by pulling them apart.

Front

What is cytokinesis?

Back

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

Front

How do the daughter cells compare to the parent cell after mitosis?

Back

The daughter cells are identical to the parent cell in terms of chromosome number and genetic content.

Front

What is the role of centromeres in mitosis?

Back

Centromeres are the regions of chromosomes where sister chromatids are joined and where spindle fibers attach during mitosis.
