Transcription and Regulation Immediately after transcription a methylated guanine cap is added to the 31 end of the transcript a methylated guanine cap is added to the 51 end of the transcript both (a) and (b) a poly adenylation signal is added a methylated guanine cap is added to the 31 end of the transcript a methylated guanine cap is added to the 51 end of the transcript both (a) and (b) a poly adenylation signal is added ANSWER DOWNLOAD EXAMIANS APP
