Ramachandran plots can help increase the accuracy of models derived from x-ray crystallography data. The plot below was created by measuring phi, and psi for each amino acid residue in a 2.2 A resolution crystal structure. In the plot, which excludes Gly and Pro residues, selected residues (dots) are numbered 1 through 5.
Which of the following statements can be correctly stated for this plot in reference to selected residues?
A. Residues 1 and 3 are in either B sheets
B. residue 2 is in a right-handed a helix, and residue 4 is in a left-handed a helix.
C. If residue 5 were Gly, it might be in an acceptable position in the plot
