Transcription and Regulation Immediately after transcription a poly adenylation signal is added both (a) and (b) a methylated guanine cap is added to the 51 end of the transcript a methylated guanine cap is added to the 31 end of the transcript a poly adenylation signal is added both (a) and (b) a methylated guanine cap is added to the 51 end of the transcript a methylated guanine cap is added to the 31 end of the transcript ANSWER DOWNLOAD EXAMIANS APP
Transcription and Regulation Most transcripts of protein coding genes are cleaved at the 3' end just before a poly adenylation signal at the 5' end immediately after a poly adenylation signal at the 3' end just after a poly adenylation signal at the 5' end immediately before a poly adenylation signal at the 3' end just before a poly adenylation signal at the 5' end immediately after a poly adenylation signal at the 3' end just after a poly adenylation signal at the 5' end immediately before a poly adenylation signal ANSWER DOWNLOAD EXAMIANS APP
