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?

Chapter 12 Problem 34
Question
The fidelity of protein synthesis is assured twice during protein synthesis. How and when?
Solution
Step 1 of 3
The fidelity of protein synthesis is assured through two key mechanisms during the process: Aminoacyl-tRNA Synthetases and Ribosome Proofreading
Aminoacyl-tRNA Synthetases (During tRNA Charging):
Aminoacyl-tRNA synthetases play a crucial role in maintaining fidelity during protein synthesis.
These enzymes attach the correct amino acid to the corresponding tRNA molecule, a process known as tRNA charging.
Each aminoacyl-tRNA synthetase specifically recognizes and binds to its corresponding amino acid and tRNA molecule to ensure accurate pairing.
