Mitosis Review

Front

What is mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the original cell.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase, often abbreviated as PMAT.

Front

What happens during prophase?

Back

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

Front

What occurs during metaphase?

Back

During metaphase, chromosomes line up at the cell's equator, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is anaphase?

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

Front

What happens in telophase?

Back

In 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 daughter cells?

Back

Daughter cells are the two new cells that result from the division of a single parent cell during mitosis.

Front

How many chromosomes do daughter cells have after mitosis if the parent cell has 24 chromosomes?

Back

Each daughter cell will have 24 chromosomes, the same number as the parent cell.

Front

How many pairs of chromosomes do humans have?

Back

Humans have 23 pairs of chromosomes, totaling 46 individual chromosomes.

Front

What is the significance of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during mitosis.
