Cell Cycle practice

Front

What happens to chromosomes during prophase of mitosis?

Back

Chromosomes form and the nuclear envelope disappears.

Front

True or False: Normal cells grow and divide continuously.

Back

False

Front

What occurs during the G1 phase of the cell cycle?

Back

The cell grows and develops.

Front

Why must cells of organisms go through cell division?

Back

For growth, repair of damaged cells, and replacement of dying cells.

Front

What is the process called that divides the cytoplasm and organelles between two new cells after mitosis?

Back

Cytokinesis.

Front

What is the main purpose of the cell cycle?

Back

To ensure proper growth, development, and division of cells.

Front

What are the main phases of the cell cycle?

Back

Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers separate chromosomes to opposite poles of the cell.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.
