The Cell Cycle and Mitosis Review (5th) - Duncan

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 Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What occurs during prophase?

Back

During prophase, 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 align at the cell's equatorial plane and spindle fibers attach to centromeres.

Front

What happens during anaphase?

Back

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

Front

What is telophase?

Back

Telophase is the final stage of mitosis where chromosomes de-condense, the nuclear envelope re-forms, and the cell prepares to divide.

Front

What is a tumor?

Back

A tumor is a mass of cells that forms when the cell cycle is not regulated, leading to uncontrolled cell division.

Front

What is the role of spindle fibers?

Back

Spindle fibers are structures that help separate chromosomes during cell division by attaching to centromeres.
