Lesson Plan: Title Transcription Part II: What happens to the initial (premRNA) transcript made by RNA pol II? Objectives  Explain how the transcript generated by RNA polymerase II (the pre-mRNA) is processed to become mature mRNA, using the sequence signals identified in Module 2.  Use the genome browser to analyze the relationships among: 1. pre-mRNA 2. 5’ capping 3. 3’ polyadenylation 4. splicing 5. mRNA Pre-requisites  Modules 1 and 2  Define pre-mRNA as the RNA ...
