Question

Which of the following mRNA codons will bind to the tRNA anticodon 5' GCU 3', considering wobble–base pairing rules. Select one:

a. 5' CGA 3'
b. 5' AGU 3' and 5' AGC 3'
c. 5' AGC 3'
d. 5' UGA 3' and 5' CGA 3'

Answer 1

a. 5' CGA 3

Step-by-step explanation:

The wobble type of base pairing also comprises the base pairs formed by inosine (I) also called hypoxanthine with Cytosine(C), Thyamine(T), or Adenine (A),

Where purine base pairs A to G(or I), A to A, and G to C.

Where

5' GCU 3' pairs with

5' CGA 3

Therefore G pairs to C, C pairs to G, U pairs with A.
