Cell cycle, mitosis, and cancer

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).

Front

During which phases of the cell cycle does the cell grow?

Back

The cell grows during the G1 and G2 phases.

Front

What are chromatids?

Back

Chromatids are the two exact copies of DNA that make up a chromosome.

Front

What is the purpose of the cell cycle?

Back

The purpose of the cell cycle is the growth of an organism and the repair of damaged tissue.

Front

What is a centromere?

Back

A centromere is the structure that holds two chromosomes together until they separate during cell division.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells.

Front

How does cancer affect the cell cycle?

Back

Cancer disrupts the normal regulation of the cell cycle, leading to uncontrolled cell growth and division.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are mechanisms that ensure the cell is ready to proceed to the next phase of the cell cycle, preventing errors.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that eliminates damaged or unnecessary cells.
