The tRNAs were chosen such that they did not require modifications after synthesis. Evolutionary conservation of the identity elements in tRNAs suggests their importance, even though these elements do not directly contribute to protein synthesis. Species trees (blue) become pruned over time via extinction, while gene ancestry (red) from extinct lineages can be preserved by the HGT event, resulting in a gene ancestor predating the LUCA species ancestor. ; Kim, M.H.

Cell-free systems opened up the possibility to work with a range of organisms from conventional model organisms such as E. coli and yeast to more un-conventional systems such as Bacillus megaterium (Moore et al., 2018), Clostridium autoethanogenum (Krger et al., 2020), and eukaryote-derived systems such as rabbit reticulocyte lysate (Gagoski et al., 2016). While using a nonsense codon, a stop codon (UAG, UGA, and UAA) is reassigned to incorporate NC-AA instead.
