Figure 7.6 Wobble in base pairing allows some bases at the first position of the anticodon one base in the third position of the codon. Pairin bases is extended from the G-C and A-U pairs 7.3 tRNA contains to the G-U wobble pait. Base modifications may restrict or extend the pattem Modification to 2-thiouridine restricts pairing to a alone because only one H-bond could form with G Modification to inosine allows pairing with U C, and A modified bases that influence its pairing Standard base properties Sugar. Guanine Adenine Trace G-U wobble paining Guanine Figure 7.7 Modification to 2-thiouracil pairs only with A inosine allows Thiouracil Guanine pairing with U Adenine Inosine has mutiple pairs C and a Cytosine Inosine Sug 消当 inosine Sugar InosineFigure 7.7 Modification to inosine allows pairing with U, C, and A. 7.3 tRNA contains modified bases that influence its pairing properties
