Cell Cycle & DNA

Front

What is the purpose of the cell cycle checkpoints?

Back

To ensure that the cell cycle phases proceed only when the cell is ready.

Front

What stage of the cell cycle comes after all the others?

Back

Identical daughter cells are created.

Front

What is the result of DNA replication?

Back

Two DNA molecules, each with one new strand and one original strand.

Front

What is the sugar found in the DNA molecule?

Back

Deoxyribose.

Front

In which phase of mitosis do the chromosomes line up along the 'equator'?

Back

Metaphase.

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 the duplication of chromosomes.

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the progression of the cell cycle by activating cyclin-dependent kinases (CDKs).

Front

What happens during prophase of mitosis?

Back

Chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What is the significance of the G1 checkpoint?

Back

The G1 checkpoint assesses cell size, DNA integrity, and nutrient availability before the cell enters the S phase.
