however, a transversion occurred which changed the G nucleotide to T, what outcome(s) are likely?   a. transcription levels would decrease because the promoter would be weaker   b. nothing would happen because the promoter would not change the mRNA sequence   c. the mutation would block RNA polymerase from binding to the DNA   d. transcription levels would increase because the promoter would be stronger   e. the bio gene does not require a functional promoter

Which of the following statements about trp operon regulation is TRUE? A. Low trp levels result in trp repressor binding. O B. High trp levels result in transcriptional antitermination. C. Low trp levels cause the ribosome to fall off at the trp codons in the upstream ORF. O D. High trp levels cause the ribosome to fall off at the trp codons in the upstream ORF. O E. Low trp levels result in transcriptional antitermination.
