The 3D molecular structures of biological molecules can be determined using the following techniques. Select all that apply:
I. light microscopy
II. electron microscopy
III. NMR
IV. x-ray crystallography

Question

Quizplus · Accepted Answer

II, III, and IV (electron microscopy, NMR, and x-ray crystallography) are techniques used to determine the 3D structures of biological molecules. Light microscopy does not have the resolution necessary for determining molecular structures at the atomic level.
