Question

Which position on the anticodon is the wobble position?

a. 5' end
b. 3' end
c. middle of the anticodon
d. 5' end or 3' end
e. any position can be the wobble position

Answer 1

A. 5' end

Step-by-step explanation:

Wobble base refers to the specific base of some tRNA anticodons that have the ability to pair with more than one kind of base in codon. There is a total of 61 codons for 20 amino acids but only 20 different tRNAs.

A wobble base allows a specific tRNA anticodon to recognize and pair with more than one mRNA codon. The 5' base of the anticodon (the third nucleotide in an anticodon) can form hydrogen bonds with more than one type of 3' base of mRNA codon.

For example, Inosinate present at the 5' end of anticodon can pair with as many as three different nucleotides (U, C, and A).
