22. Some tRNAs contain inosine, which can base pair with A, C, and U. Why might this be advantageous with ate but not ambiguous? olyp min 33. What is required for molecular surfaces/interfaces to interact with one another for a sufficient amount of time (such as an antibody/antigen)?

What are two possible anticodon sequences for tRNA's that are charged with Phenylalanine (Phe)? O 3' AAU 5' and 3' GAA 5' O 3' AAA 5' and 3' AAG 5 3' UUG 5' and 3' CUG 5' O 3' GAA 5' and 3' CAG 5' 3' GUA 5' and 3' GUG 5'
