________ can be used to determine the amino acid sequence of a protein or peptide.
A) X-ray crystallography
B) Nuclear magnetic resonance
C) Mass spectrometry
D) The ChIP assay

Question

Quizplus · Accepted Answer

Mass spectrometry can determine the mass of individual amino acids in a protein or peptide, which can then be used to determine the sequence of amino acids present. X-ray crystallography and nuclear magnetic resonance are used to determine the three-dimensional structure of proteins, but not necessarily their amino acid sequences. The ChIP assay is used to analyze protein-DNA interactions.
