Cell Cycle, Division, and Cancer

Front

What is a malignant tumor?

Back

A malignant tumor is a type of cancerous tumor that can spread to other parts of the body.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal functions.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, the DNA in the cell is copied.

Front

What is a checkpoint in the cell cycle?

Back

A checkpoint is a critical point where stop and go signals can regulate the cell cycle.

Front

What occurs during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell grows a little bit more.

Front

What is the purpose of the cell cycle?

Back

The cell cycle is the process by which a cell grows, duplicates its DNA, and divides to produce new cells.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors do not spread to other parts of the body, while malignant tumors can invade nearby tissues and spread.

Front

What role do growth factors play in the cell cycle?

Back

Growth factors are proteins that stimulate cell division and growth.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

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

Back

The S phase is significant because it ensures that each daughter cell receives an identical set of chromosomes.
