1.	In the consensus sequence 5′-AG/GUAAGU–intron–YNCURAC–YnNAG/G-3′Y could be ______(a) Base A(b) Base G(c) Base C(d) Base TThis question was posed to me by my school teacher while I was bunking the class.The above asked question is from Post-Transcriptional Modification in portion Gene Expression : Transcription Prokaryotes of Cytogenetics
Answer» The CORRECT choice is (c) Base C The explanation is: Y could be any pyrimidine that RULES out A and G as base. Now we know that RNA doesn’t have T, so the only pyrimidine possible from the given COMBINATION is C.
