Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What occurs during interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis. It consists of three stages: Gap 1 (G1), Synthesis (S), and Gap 2 (G2).

Front

Define mitosis.

Back

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter nuclei, each with the same number of chromosomes as the parent cell.

Front

What is cytokinesis?

Back

Cytokinesis is the division of the cytoplasm that occurs after mitosis, resulting in two separate daughter cells.

Front

List the phases of mitosis in order.

Back

The phases of mitosis in order 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 the mitotic spindle begins to form.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

Front

Define centromere.

Back

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

Front

What occurs during metaphase?

Back

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