given humans have 64 possible codons, I am imagining a crowd of tRNA, each carrying an amino acid, swarming clumsily with random thermal motion around a ribosome with a feed of mRNA. How do the tRNA anti-codons find the right mRNA codons so quickly?! I saw a video that shows the amino acids zipping together at about the speed of zipping up a zipper. Based on random thermal motion and the crowd with great variety of anti-codons, making the right match so quickly seems impossible. I know there are protein catalysts involved, but...?
