Question

Select the correct one (w.r.t. Wobble hypothesis)
(1) Third base of a codon lacks vibrating capacity
(2) Third base can establish H-bonds even with the non complementary anticodon
(3) Specificity of a anticodon is particularly determined by first two codon
(4) Major cause of degeneracy is the first two N-bases of codon

Please explain why the answer cannot be (4). The correct ans given is (2). Please explain the 2nd option also

Answer 1

2)third base can establish H-bond even with the non non complementary anticodon
