The best description of how allosteric regulation works is that a ligand __________ the transcriptional regulatory protein,which __________ the protein's affinity for DNA.

Question

Quizplus · Accepted Answer

Allosteric regulation involves a ligand binding to a regulatory protein, causing conformational changes that affect the protein's activity. In this case, the ligand binding to the transcriptional regulatory protein affects its affinity for DNA. There is no mention of covalent modification in the question stem, so choices A and B are incorrect. Choice D is incorrect because allosteric regulation can either increase or decrease a protein's activity.
