Question

C. The primary structure is the linear sequence of amino acids linked together in a polymer (determined by the genetic code è mRNA codons). Draw the chemical structure of the primary structure of the SerCys-Lys polymer (with the appropriate covalent bonds) that would result if the ribosome completed the condensation reactions. Clearly label the N- and C- terminus of the polypeptide.
