Question

Which of the following is a Wobble base pairs?

• A. Guanine-uracil (G-U)
• B. Hypoxanthine-uracil (I-U)
• C. Hypoxanthine-adenine (I-A)
• D. All of the above

Answer 1

The correct option is D All of the above

In Wobble base pairing, the pairing of the third base varies according to the base at this position, for example, G may pair with U. The conventional pairing (A = U, T, G = C) is called Watson-Crick pairing and the second abnormal pairing is called wobble pairing. Three types of wobble pairings are know

a) U pairs with G

b) G pairs with U

c) I pairs with A, U or C.

So, the correct answer is 'All of the above'
