Quizplus · Accepted Answer

Ramachandran plots show the distribution of phi (ϕ) and psi (ψ) angles in proteins. Only a limited set of phi-psi angles are commonly found in protein structures, hence option A is correct. The other options are incorrect as Ramachandran plots do not show the configuration of the chiral carbon in amino acids, the linearity of peptide backbones, or the chirality of the alpha-carbon.
