What is the relationship between checkpoints and the cyclin-CdK complexes?
Checkpoints are the regulatory points in the cell cycle, and their function is carried out by the interactions between cyclins and CdKs.
If a cell's internal controls fail, what are two possible outcomes for the cell or organism?
If cell cycle controls are disrupted, it can lead to cancer or programmed cell death (apoptosis).
What is the primary role of checkpoints in regulating the cell cycle?
Checkpoints regulate progression through the cell cycle, ensuring that one phase is complete before the next begins.
What are cyclins and cyclin-dependent kinases (CdKs)?
Cyclins and cyclin-dependent kinases (CdKs) are molecules whose interactions control the cell cycle.
What is apoptosis?
Apoptosis is programmed cell death, which can be a consequence of disruptions to the cell cycle.
A cell repeatedly fails to pass a checkpoint due to DNA damage. What process might be initiated?
If a cell cannot repair damage detected at a checkpoint, it may undergo programmed cell death, or apoptosis.
What are checkpoints in the context of the cell cycle?
Checkpoints are internal controls that regulate the progression through the cell cycle.
How is the cell cycle controlled at a molecular level?
The cell cycle is controlled by interactions between cyclins and cyclin-dependent kinases (CdKs).
What is a major condition that can result from disruptions to the cell cycle?
Disruptions to the cell cycle can lead to uncontrolled cell growth, resulting in conditions like cancer.
What is the general effect of disruptions to the cell cycle?
Disruptions to the cell cycle negatively affect the cell or organism, potentially leading to diseases or cell death.
