G)
You also study the expression of different mutants for this gene.
Mutant C has had the first 5 base pairs deleted (position 1-5). Does this mutation change the
sequence of the protein produced? Why or why not? If it does change the sequence of protein be
sure to write out the new sequence. If it does not change the protein sequence, what effect (if any)
would you expect it to have on expression of the gene?
For mutant C answer the following:
Does this mutation change the sequence of the protein produced? Why or why not?
If it does change the sequence of protein be sure to write out the new sequence.
If it does not change the protein sequence, what effect (if any) would you expect it
to have on expression of the gene?
