Electron Microscopy, X-Ray Crystallography and NMR Spectroscopy Are Used to Determine

Electron microscopy, x-ray crystallography and NMR spectroscopy are used to determine 3D structures of biomolecules. Using protein examples studied in chapter 3, which statements are true?

A) The structure of insulin can easily be studied in solution using NMR, since insulin has a small molecular weight.
B) The structure of immunoglobulin can be determined by electron microscopy.
C) Fragments of immunoglobulin 11ef2e34_c901_7ebf_a6da_5387e8b94d05_TB9579_11 can be determined by x-ray crystallography.
D) X-ray crystallography is well-suited for determining the 3D structure of hemoglobin.
E) all of the above
