WebA transfer RNA ( tRNA) is a special kind of RNA molecule. Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon. The … The A site accepts an incoming tRNA bound to an amino acid. The P site holds a tRNA … Webdeacylation step are either tRNA and the dissociated AA (if tRNA was charged) or only tRNA. After an empirically determined time following filtration of the smaller molecules, NaOH is added to the filter input (Figure 2c, top) for deacylation of the tRNA-AA complex.
