Question

Which technique would be most useful if you were interested in learning about a protein's function and about the proteins with which it interacts?

1) X-ray crystallography
2) Mass spectrometry
3) Western blotting
4) Polymerase chain reaction

Answer 1

Mass spectrometry is the most useful technique for studying a protein's function and interactions with other proteins.

Step-by-step explanation:

The most useful technique for learning about a protein's function and the proteins it interacts with is mass spectrometry.

Mass spectrometry is used to identify and determine the characteristics of a molecule. It has allowed researchers to analyze very small protein samples. Other techniques like X-ray crystallography and protein microarrays are also used to study protein structures and interactions.
