Initials (first and last)__________ GENE3200 – Summer 2010 – Bedell – KEY Quiz 4 – 6/29/10 ID no. 810-_________________________ 1. (2 pts). Given the mRNA sequence shown below, write the sequence and indicate the 5’ and 3’ ends of the corresponding template strand of DNA. 5'-GUCCCAGUAGCCAAU-3' 3’-CAGGGTCATCGGTTA–5’ 2. The sequence below is a small portion of a eukaryotic pre-mRNA (primary mRNA) . Note that N 50 indicates a 50 nt sequence with N being any base. You can assume that a consensus branchpoint sequence is included in the sequence but is not shown here. 5’-CAAUGCCCAGGUAAUUCUAUGAUN 50 AUCUGCUGGACCCCTTTTTAGCUAAAUC 3’ 2A.
