BIOCHEMISTRY C785 OA EXAM QUESTIONS AND ANSWERS LATEST 2024 (GRADED) Choose the correct coding strand (non-template) from this template (non-coding) DNA: 5' ACG GTA 3' (1/1 Points) 5' UAC CGU 3' 3' UAC CGU 5' 3' TAC CGT 5' 5' TAC CGT 3' Correct! First, note that we are asked for a template/non-coding strand of DNA. DNA uses the base T where RNA uses the base U. Therefore, we can eliminate the two answers containing U because they must be RNA and we want DNA. Then, recall that ...
