BCH2333 we can differentiat DNA from RNA by - Answer- looking for 2'-OH and bases in sequence (U vs. T) Purines are connect to phosphate backbone at _____ and Pyrimidines at _____ - Answer- Purines connected to sugar phosphate backbone at N9 Pyrimidines connected to backbone by N1 All bases are connected to ________ - Answer- anomeric C (C1') by b-linkage chirality of amino acids and the preference for L-enantiomers results in: - Answer- 1.Protein surface asymmetry --> very sp...

What are the four rules for writing resonance structures? Correct Answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? Correct Answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple bond. The latter comprom...
