**Cell Cycle and Mitosis

Front

What is the purpose of cell replication in organisms?

Back

Cell replication is necessary for growth, repair of damaged cells, and replacement of dying cells.

Front

What does chromatin refer to?

Back

Chromatin refers to DNA that is relaxed like a bowl of spaghetti.

Front

What stage of mitosis involves the pulling apart of sister chromatids?

Back

Anaphase is the stage of mitosis where the sister chromatids are pulled apart.

Front

What does NOT happen during interphase?

Back

Cell division does not happen during interphase.

Front

At what stage during mitosis does the nuclear envelope break up?

Back

The nuclear envelope breaks up during Prophase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What occurs during the S phase of interphase?

Back

During the S phase, DNA replication occurs.

Front

What is the role of the spindle fibers during mitosis?

Back

Spindle fibers help separate the sister chromatids and pull them to opposite poles of the cell.

Front

What is cytokinesis?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells after mitosis.

Front

What happens during prophase?

Back

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