You identify a proflavin-generated allele of a gene that produces a 110-amino acid polypeptide rather than the usual 157- amino acid protein. after subjecting this mutant allele to extensive proflavin mutagenesis, you are able to find a number of intragenic suppressors located in the part of the gene between the sequences encoding the n-terminus of the protein and the original mutation but no suppressors located in the region between the original mutation and the sequences encoding the usual c-terminus of the protein. why do you think this is the case?
