provides information on the structure of a purified protein based on its nuclear spin properties in a magnetic field, whereas uses diffraction pattern of proteins in solid phase.

Nuclear magnetic resonance provide information on the structure of a purified protein based on its nuclear spin properties in a magnetic field, whereas X-Ray crystallography uses diffraction pattern of protein in solid phase.

Explanation:

Nuclear magnetic resonance is a spectroscopic technique that involves change in nuclear spin energy in presence of an external magnetic field. It is based on the absorption of electromagnetic radiation in the radio-frequency region.

X-Ray crystallography is a method of determining the arrangement of atoms within a crystal.This technique is based the fact that when a beam of X-ray strikes a crystal, the beam gets diffracted. From the angle and intensities of diffraction a three-dimensional structure of electron density can be determined .

he is very short, and he can only reach halfway up on the elevator buttons. but on a rainy day, he has his umbrella with him, and he uses it to poke the button at the top.

the answer is c. altitude. hope this ! #brainiac
