7. NC EOC Review: The Cell Cycle & Cancer RB

Front

What causes cancer cells to behave differently than healthy cells?

Back

Mutations in their DNA.

Front

During which phases is the cell growing as it prepares for division?

Back

G1 and G2.

Front

What happens during prophase?

Back

DNA condenses into chromosomes and the nuclear envelope begins to disappear.

Front

Which phase of mitosis involves the separation of sister chromatids?

Back

Anaphase.

Front

Which phase of mitosis is characterized by the alignment of chromosomes at the cell's equator?

Back

Metaphase.

Front

What is interphase?

Back

The phase of the cell cycle where the cell is not actively dividing, consisting of G1, S, and G2 phases.

Front

What is the role of the G1 phase in the cell cycle?

Back

The cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

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

Front

What is the significance of the G2 phase?

Back

The cell continues to grow and prepares for mitosis, ensuring all DNA is replicated.

Front

What is the main purpose of mitosis?

Back

To divide the cell's nucleus and distribute the duplicated chromosomes into two daughter cells.
