My basic question is this: how does a free tRNA, with an amino acid already attached, "know" to go and bond with the appropriate corresponding codon on the mRNA already being processed in the ribosome? Is it that tRNAs from the cytoplasm all attempt to fit, and only the one that does works, or is it more organized than this, using some sort of messenger chemical? I know that each tRNA has a corresponding amino acid, and that they are attached outside of the ribosome. My question is how the already paired amino acids and tRNAs "know" to go the appropriate codons at the A space in the ribosome.
