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 and the mitotic phase.

What are the three phases of interphase?

Back

The three phases of interphase are G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

What happens during the S phase of interphase?

Back

During the S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

What occurs during prophase?

Back

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

What is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equatorial plane.

What happens during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell.

What is cytokinesis?

Back

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

Why is DNA replication important before cell division?

Back

DNA replication is crucial to ensure that each daughter cell receives an identical set of genetic information.
