Question

Which of the following is not a wobble base pair and how?
(1) G - U
(2) I - U
(3) I - A
(4) A - T

Answer 1

Wobble base pairs are non-standard pairs in the structure of RNA which include G-U, I-U, I-A and I-C.
Among the suggested options only A-T is a standard pair. The rest ones are non-standard.
Thus, correct answer is (4) A-T
