Genetics final study guide intro to molecular genetics mls 400 oakland Genetics Final Exam Important definitions Base: pyrimidines & purines (C, U, T) (A, G) Nucleoside: base + sugar (phosphorylated to become a nucleotide) Nucleotide: phosphate group + sugar + base Sugar may be ribose (RNA) or deoxyribose (DNA - missing hydroxyl group) Antiparallel: 2 sequences have opposite orientation with regard to their 5’ & 3’ ends Complementary: AT/GC rule; purines bond to pyrimidines, and vice ...

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 ...
