Several examples of antisense RNA regulating translation in bacterial cells have been discovered. Molecular geneticists have also used antisense RNA to artificially control transcription in both bacterial and eukaryotic genes. To inhibit the transcription of a bacterial gene with antisense RNA, what sequence might the antisense RNA contain? a sequence complementary to the structural gene a sequence complementary to the promoter of the operon a sequence that is identical to the gene that codes for RNA polymerase a sequence complementary to a 5' UTR a sequence complementary to the 3' UTR
