Cell Cycle and Cell Division

Front

What is the purpose of the mitosis cell cycle?

Back

To make more of the same cells, for growth and repair, and to prevent the cell from becoming too large.

Front

What happens during prophase in the cell cycle?

Back

The nuclear membrane breaks down and disappears, and chromatin condenses into chromosomes.

Front

What is the phase of mitosis where chromosomes are pulled apart to opposite ends of the cell?

Back

Anaphase.

Front

How does cytokinesis differ in plant and animal cells?

Back

Plant cells form a cell plate, while animal cells form a cleavage furrow.

Front

What is cancer in relation to cell division?

Back

Cancer is the uncontrolled division of cells, specifically uncontrolled mitosis.

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the main stages of the cell cycle?

Back

The main stages are interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What occurs during the S phase of interphase?

Back

DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the role of the spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite ends 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.
