So we have the five end of our RNA molecule and we have the three end of that RNA molecule. And each one of these circles designates a single nucleotide. Now, these red regions are the regions where there is hydrogen bonding taking place between the tRNA nucleotides. So we have bonding here, here, here, and here taking place. Now, there are two important locations on the transfer RNA molecule that you have to be aware of. We have the three end that contains the proper nucleotide sequence that is responsible for binding to our amino acid.
