AP Bio Insta-Review Topic 4.6*: Cell Cycle

Front

What is Independent Assortment?

Back

Independent Assortment is the principle that states that alleles for different traits are distributed to gametes independently of one another. In the context of the cell cycle, it does NOT occur during mitosis.

Front

What phase of mitosis involves the formation of two nuclear envelopes?

Back

Telophase is the phase of mitosis when two nuclear envelopes form around the separated sets of chromosomes.

Front

Which phase of interphase is primarily responsible for cell growth?

Back

All phases of interphase (G1, S, and G2) involve cell growth.

Front

During which phase of mitosis do sister chromatids align at the cell's equatorial plate?

Back

Metaphase is the phase of mitosis when sister chromatids align on the metaphase plate in the middle of the cell.

Front

True or False: The cell grows through all three phases of interphase.

Back

True. The cell grows during G1, S, and G2 phases of interphase.

Front

What is the purpose of the cell cycle?

Back

The cell cycle is the series of events that lead to cell division and replication, allowing for growth, development, and repair.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M phase, which includes mitosis and cytokinesis).

Front

What occurs during the G1 phase of interphase?

Back

During the G1 phase, the cell grows in size, produces RNA, and synthesizes proteins necessary for DNA replication.

Front

What happens during the S phase of interphase?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle, preventing errors such as DNA damage or incomplete replication.
