82. Which one of the following statements is NOT correct?
(A) A major objective of proteomics is to identify all of the proteins present in a cell under different conditions.
(B) Tandem mass spectrometry has largely replaced the Edman method for the identification of peptides and proteins.
(C) In electrospray ionization mass spectrometry, molecules of a single protein produce a family of peaks, with each successive peak corresponding to a protein ion with one additional charge and a correspondingly lower m/z value.
(D) Since mass is a universal property of all atoms and molecules, mass spectrometry is ideally suited to the detection of posttranslational modifications in peptides/proteins.
(E) Time-of-flight mass is a method to make molecules bear electric charges.
