Cleavage of a polypeptide by CNBr and chymotrypsin yielded fragments with the following amino acid sequences:CNBr treatment:1. Arg-Ala-Tyr-Gly-Asn2. Leu-Phe-Met3. Asp-MetChymotrypsin4. Met-Arg-Ala-Tyr5. Asp-Met-Leu-Phe6. Gly-Asna). What is the sequence of the intact polypeptide? Please show the sequence in one-letter abbreviations. b). Please draw the structure of the first CNBr peptide. c). Does this peptide absorb ultraviolet light? Explain. d). If you cleave this peptide with trypsin, what fragments you will get?e). Please estimate the molecular weight of this peptide.
