Back

cyclin

Front

What is a disorder in which some of the body's cells lose the ability to control growth?

Back

Front

What are the two types of regulators that control the cell cycle?

Back

internal and external regulators

Front

What does cyclin regulate?

Back

Cell Cycle

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins activate cyclin-dependent kinases (CDKs) to regulate progression through the cell cycle.

Front

What are cyclin-dependent kinases (CDKs)?

Back

Enzymes that, when activated by cyclins, regulate the cell cycle by phosphorylating target proteins.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints ensure that the cell cycle progresses only when certain conditions are met, preventing errors.

Front

What can happen if the cell cycle is not properly regulated?

Back

Uncontrolled cell division can lead to cancer.

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 not functioning properly.
