STUDY GUIDE: Cell Cycle

Front

What is the process of DNA replication called?

Back

Semi-conservative replication, resulting in two identical molecules, each with one original strand and one new strand.

Front

During which phase of the cell cycle is DNA replicated?

Back

Synthesis (S phase) of the cell cycle.

Front

What is the condensed form of DNA found during mitosis called?

Back

Chromosome.

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 forming cells after mitosis?

Back

Cytokinesis.

Front

What are the main stages of the cell cycle?

Back

Interphase (G1, S, G2) and Mitosis (M phase).

Front

What happens during the G1 phase of the cell cycle?

Back

Cell growth and preparation for DNA synthesis.

Front

What is the role of the centromere during cell division?

Back

It holds sister chromatids together and is the attachment point for spindle fibers.

Front

What is chromatin?

Back

The relaxed form of DNA found in the nucleus during interphase.

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.
