Unformatted text preview: 1.What are the possible codons for the Tyr residue that is changed in the double mutant? 2.Does any frameshift single nucleotide addition or deletion result in changing that Tyr residue to Phe? 3.How does that result in changing also the Leu residue to Cys and Ser to His? 4.In a gene copy with the original frameshift mutation (Tyr to Phe), what 2 nd mutant could give rise to Gly at the 7 th residue (ie after His)? 5.Would your choice of 2 nd mutant lead to the normal Ala residue next in line?...
