The Cell Cycle and Mitosis Review (6th)

Front

What is cytokinesis?

Back

Cytokinesis is the process of splitting the cytoplasm and cell membranes to form two separate daughter cells after mitosis.

Front

In which phase of mitosis does cytokinesis begin?

Back

Cytokinesis begins in the telophase of mitosis.

Front

What occurs just before the cell enters the G2 stage of the cell cycle?

Back

DNA replicates just before the cell enters the G2 stage.

Front

What is a chromosome?

Back

A chromosome is a structure made of DNA and proteins that contains genetic information.

Front

What is prophase in mitosis?

Back

Prophase is the first stage of mitosis where the chromatin condenses into visible chromosomes and the nuclear membrane begins to disintegrate.

Front

What is the role of centrioles during mitosis?

Back

Centrioles help in organizing the mitotic spindle, which is essential for chromosome movement during mitosis.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to their centromeres.

Front

What is anaphase?

Back

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

Front

What occurs during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear membrane re-forms, and the chromosomes begin to de-condense.

Front

What is the function of the centromere?

Back

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