In Studying an E

In studying an E.coli strain containing a known frameshift mutation,you isolate a mutant in which this frameshift is suppressed.You therefore expect to find which of the following associated with the suppression? (Assume the frameshift has not been corrected in the coding for the peptide.)

A) suppressor tRNAs encode an amino acid for a stop signal
B) suppressor tRNAs encode a four-nucleotide anticodon
C) suppressor tRNAs encode a two-nucleotide anticodon
D) both choices B and C
E) all of the above
