Detailed explanation-1: -Which of the following describe(s) cyclin-dependent kinase (Cdk)? Cdk is present throughout the cell cycle and is an enzyme that attaches phosphate groups to other proteins.

Detailed explanation-2: -Summary. Cyclin-dependent kinases (CDKs) are protein kinases characterized by needing a separate subunit-a cyclin-that provides domains essential for enzymatic activity. CDKs play important roles in the control of cell division and modulate transcription in response to several extra-and intracellular cues.

Detailed explanation-3: -CDKs are a family of multifunctional enzymes that can modify various protein substrates involved in cell cycle progression. Specifically, CDKs phosphorylate their substrates by transferring phosphate groups from ATP to specific stretches of amino acids in the substrates.

Detailed explanation-4: -Which of the following statements regarding cyclin-dependent protein kinase is not correct? Explanation: They remain constant throughout cell cycle.
