4. A peptide was cleaved into smaller fragments using chymotrypsin and CnBr. The fragments were separated by HPLC and then sequenced by Edman degradation. Determine the sequence of the original peptide from the following fragment sequences.

Sickle cell hemoglobin DNA CACGTAGACTGAGG ACAC.. Sickle cell hemoglobin MRNA Sickle cell hemoglobin AA sequence 4. What type of mutation is this? Please explain why.

1. You are investigating a protein that has the amino acid sequence N ... Ala – Thr - Asn – Trp – Lys - Arg - Gly – Phe – Thr ... C within its primary structure. You found that several of the mutations affecting this protein produced shortened protein molecules that terminated within this region. In one of the mutants, the Asn became the terminal (last) amino acid. (a) What DNA single-base changes(s) would cause the protein to terminate at the Asn residue? (b) What other potential sites do you see in the DNA sequence encoding this protein where mutation of a single base pair would cause premature termination of translation? >
