Question
It is possible for the codons for a single amino acid to have the first two bases in common and to differ in the third base. Why is this experimental observation consistent with the concept of wobble?
Solution
Step 1 of 2
The concept of wobble refers to the flexibility in base pairing rules between the codon on mRNA and the anticodon on tRNA during protein synthesis. It explains that a codon's first two nucleotide bases on mRNA often have strict base-pairing rules with the corresponding nucleotide bases of the anticodon on tRNA. However, the third base of the codon and the anticodon pair with more flexibility, allowing for variations and non-standard base pairing.
