Question

video.
both cyclin and cdk are what type of
macromolecule?

nucleic acid

protein

carbohydrate

lipid

rewatch

Explanation:

Cyclins are regulatory molecules that bind to Cyclin-Dependent Kinases (CDKs), which are enzymes. Enzymes and regulatory cyclins are both composed of amino acid chains, classifying them as proteins. Nucleic acids store genetic information, carbohydrates provide energy, and lipids form membranes/act as signaling molecules, which do not match the identity of cyclins and CDKs.

Answer:

Protein
