Cell Cycle & DNA

Front

Why is DNA replication important before a cell divides in mitosis?

Back

To ensure that genetic information is accurately transferred to daughter cells.

Front

How can cancer be defined in relation to cell division?

Back

Cancer can be defined as uncontrolled cell division.

Front

What is the role of cell cycle checkpoints?

Back

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

Front

What phase of mitosis is characterized by chromosomes aligning at the cell's equator?

Back

Metaphase.

Front

What happens to a cell that is damaged or defective during the cell cycle?

Back

It may enter the G0 phase.

Front

What are the main phases of the cell cycle?

Back

The main phases are 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 during the S phase.

Front

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

Back

The G1 phase is important for cell growth and preparation for DNA synthesis.

Front

What is the function of the G2 phase in the cell cycle?

Back

The G2 phase is for further growth and preparation for mitosis.

Front

What is apoptosis and how is it related to the cell cycle?

Back

Apoptosis is programmed cell death that can occur if a cell is damaged or defective.
