Document Summary
Name: ___________ key_for quiz 1b___________ chem 423b, quiz 1, 8/30/2017, value: 30 points: (2 + 0. 5 pt) draw the complete chemical structure of deoxy-gtp. Draw the base only of its base-pair partner. *note: like atp, but replace a with g; ribose with deoxy- ribose. Base only for the base-pair partner (extra credit: show h-bonds to gtp. ) Which coenzyme is most likely required for this part of the reaction? (spell out coenzyme name !) What is the main function of the molecule above. Membrane; amphipathic barrier of cell (with outside: 4. (4 pt) describe the specific effect (on replication, transcription, or translation) of a mutation that inactivates the following dna sequences. Promoter: the promoter is the binding site for rna polymerase. With an inactivating mutation, transcription will not initiate. Stop codon: the stop codon signals the termination of translation. With an inactivating mutation, the ribosome will not stop at the right place--resulting protein will be too long.
