The Cell Cycle and Mitosis Test Review

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 (M).

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 (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, involving stages: prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

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

Front

What is the purpose of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms in the cell cycle that ensure proper division by checking for DNA damage, correct DNA replication, and proper attachment of spindle fibers.

Front

What happens during prophase?

Back

During 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?

Back

Spindle fibers are structures that help separate chromosomes during cell division by attaching to the centromeres and pulling them apart.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a condition characterized by uncontrolled cell growth due to failures in the regulatory mechanisms of the cell cycle, often caused by mutations or carcinogens.

Front

What occurs 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.
