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 G1, S, and G2 phases.

Front

What happens in the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, involving stages: prophase, metaphase, anaphase, and telophase.

Front

What occurs during prophase?

Back

In prophase, chromosomes condense and become visible, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes during mitosis by attaching to the centromeres and pulling them apart.

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

In telophase, the separated chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.
