The Ramachandran plot represents the phi/psi dihedral angles at each backbone peptide bond in a protein. Which one of the following statements best represents the changes observed in a dihedral angle in the transition of a prion protein from alpha-helical to beta sheet?
A. the Ramachandran plot would be identical since the amino acid sequence remains the same.
B. The phi/psi angles would change from about -60 and -50 to -140 and 135 respectively.
c. The phi/psi angles would change from about -140 and +135 to -60 and -50 respectively.
d. The phi/psi angles would change from about -60 and -50 to +140 and +135 respectively.
(the included graphic is just a graph with four quadrants with the axes labeled psi and phi with the degrees ranging from +180 to -180)
