Cell Cycle and Mitosis Concepts

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to divide and replicate. It includes interphase (G1, S, G2) and mitotic phase (Mitosis and Cytokinesis).

What happens 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 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is mitosis?

Back

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

What are spindle fibers?

Back

Spindle fibers are protein structures that help separate chromosomes during mitosis. They pull the sister chromatids apart to opposite poles of the cell.

What is the role of centrioles in cell division?

Back

Centrioles are cylindrical structures that help organize the spindle fibers during mitosis, ensuring proper separation of chromosomes.

What occurs during prophase?

Back

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

What occurs during metaphase?

Back

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

What occurs during anaphase?

Back

During anaphase, the sister chromatids are pulled apart by spindle fibers toward opposite poles of the cell.

What occurs during telophase?

Back

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

What is cytokinesis?

Back

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