For transfer RNA (tRNA), Crick hypothesized the existence of adaptor molecules, which are unstable and help carry the amino acids to the ribosomes in the cytoplasm for protein synthesis (Crick, 1955). For instance, the efficiency of NC-AA is low due to the non-compatibility of structurally diverse NC-AA with ribosomes and elongation factors (Fujino et al., 2013). In vitro synthesis of functional tRNA has made it easier to study interactions of tRNA with other components such as mRNA (Fauzi, Jack, and Hines, 2005) and AARSs (Wang et al., 2015), to investigate tRNA stability in vitro (Serebrov et al., 1998), and to determine mutational effects on tRNA function (Tamura et al., 1992).

Research that was not possible with intact cells or constrained by the limitations or complexities of the cell, was made possible by cell-free systems. Molecular evolution of aminoacyl tRNA synthetase proteins in the early history of life. In an attempt to increase the amino acid diversity to more than 20, the codon table was split for amino acids arginine, glycine, and valine and, the free codons were assigned to three distinct NC-AAs, thereby increasing the total number of amino acids to 23, in addition to the 20 native amino acids (Iwane et al., 2016).

Additional discrimination comes from the kinetic aspect of binding to discriminate cognate tRNAs. The activation of amino acids and attachment to tRNAs comprise the canonical functions of aaRSs.
