5"-3", one 3"-5") with respect to each other. (3) backbone consists of alternating sugars and phosphate groups. a. 1,2,3 b. 1,2 c. 1,3 d. 2,3 e. 1. 10 short identification- 2 pts. each: lysogeny, thymine dimer, primase, peptide bond, wobble pairing, okazaki fragment, specialized transduction, paracentric inversion, transposase, minimal medium- 5 problems (40 points total: (7 pts. ) Determine the gene order (i. e. , which gene is in the middle) from the following data set from a transduction experiment. Bacteria were selected for the presence of a+. Suppose that a mutation in the anti-codon region of a transfer rna allowed a trna which normally carries an amino acid to pair with a stop codon which leads to insertion of an amino acid during protein synthesis. What would the effect of this be on (a) a nonsense mutation involving the relevant stop codon, and (b) protein synthesis in general: (11 pts. )
