5.A - 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 mitotic phase.

Front

What are the main phases of the Cell Cycle?

Back

The main phases are Interphase (G1, S, G2) and Mitotic Phase (Mitosis and Cytokinesis).

Front

What happens during Interphase?

Back

During Interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is Mitosis?

Back

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

Front

What occurs during Prophase?

Back

During Prophase, the nuclear membrane dissolves, chromosomes condense and become visible, and spindle fibers begin to form.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes line up at the cell's equator, and spindle fibers attach to the centromeres of the chromosomes.

Front

What occurs during Anaphase?

Back

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

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear membrane re-forms, and the cell prepares to divide.

Front

What is Cytokinesis?

Back

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

Front

What is the role of spindle fibers in mitosis?

Back

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