Question

look back at the notes you took throughout the video.
positive regulators
□ serve to move a process forward.
□ serve to halt a process.
□ examples could be cyclin and cdk.
□ example could be p53.

Explanation:

Positive regulators in biological processes (like the cell cycle) act to promote and advance the process, rather than stopping it. Cyclin and CDK (cyclin-dependent kinase) are well-known positive regulators that drive the cell cycle forward, while p53 is a negative regulator that halts processes to prevent damaged cell division.

Answer:

• serve to move a process forward.
• examples could be cyclin and CDK.
