To determine the full amino acid sequence of the peptide below, you would need to run __._ cycles of the Edman degradation reaction and chromatography runs to identify the PTH-amino acid generated by each reaction. 5;66;56;65;5 The same Protein X was purified from tissue source A and tissue source B, yielding the following results: Protein X, sample A: specific activity =100U/mg; fold-purification =200 Protein X, sample B: specific activity =1000U/mg; fold-purification =100 Which of the following statements are correct? Each correctly assigned choice will earn you 0.2 marks. Protein X, sample A has a higher level of purity than Protein X, sample B. Protein X, sample B has a higher level of purity than Protein X, sample A. Tissue source A has a higher specific activity for Protein X than tissue source B. Tissue source B has a higher specific activity for Protein X than tissue source A
