1.	Which of the following is untrue?(a) RNA polymerases I is responsible for the transcription of ribosomal RNA(b) RNA polymerases III is responsible for the transcription of tRNA(c) RNA polymerase II is exclusively responsible for transcribing protein-encoding genes(d) Synthesis of mRNAs is carried out by RNA polymerase IThe question was posed to me during an online interview.My doubt stems from Promoter and Regulatory Elements in Prokaryotes & Eukaryotes topic in chapter Promoter and Regulatory Element Prediction of Bioinformatics
Answer» Right option is (d) Synthesis of mRNAs is CARRIED out by RNA polymerase I The explanation is: Ach polymerase TRANSCRIBES different SETS of GENES. RNA polymerase II is exclusively responsible for transcribing protein-encoding genes or synthesis of mRNAs.
