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 divide and replicate. It includes interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

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 happens during prophase?

Back

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

Front

What is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes line up at the cell's equatorial plane and attach to spindle fibers.

Front

What occurs during anaphase?

Back

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

Front

What is telophase?

Back

Telophase is the final stage of mitosis where the chromosomes reach the poles, decondense back into chromatin, and the nuclear envelope re-forms.

Front

What is cytokinesis?

Back

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

Front

What are spindle fibers?

Back

Spindle fibers are protein structures that help separate chromosomes during mitosis by attaching to the centromeres of chromosomes.

Front

What is the role of centrioles in cell division?

Back

Centrioles help organize the spindle fibers during cell division and are crucial for the proper separation of chromosomes.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including growth (G1), DNA replication (S), and preparation for mitosis (G2).
