11.3 Regulating the Cell Cycle

Front

What is the primary treatment for cancer that has metastasized throughout the body?

Back

Chemotherapy

Front

What are the terms used to describe non-cancerous and cancerous tumors?

Back

Non-cancerous tumors are called benign; cancerous tumors are called malignant.

Front

What are cyclins in the context of cell cycle regulation?

Back

Cyclins are internal and external regulators that control the progression of the cell cycle.

Front

What does Stage 4 cancer indicate about the spread of the disease?

Back

Stage 4 cancer indicates that the mass has spread well beyond its starting point.

Front

Define apoptosis in the context of cell biology.

Back

Apoptosis is the process of programmed cell death.

Front

What role do internal regulators play in the cell cycle?

Back

Internal regulators monitor the cell's internal environment and ensure that the cell is ready to proceed to the next stage of the cell cycle.

Front

What is the function of external regulators in the cell cycle?

Back

External regulators respond to signals from outside the cell, influencing cell division and growth.

Front

How do benign tumors differ from malignant tumors in terms of growth and spread?

Back

Benign tumors grow slowly and do not spread to other parts of the body, while malignant tumors grow rapidly and can invade surrounding tissues.

Front

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

Back

The G1 phase is the first gap phase where the cell grows and prepares for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of the genetic material.
