aminoacyl-tRNA synthetases — a universal gene (a homolog across the domains)
universal gene
aminoacyl-tRNA synthetases: charge each tRNA with its correct amino acid - the enzymes that READ the genetic code. Found in Bacteria, Archaea, Eukaryota - a homologous gene descended from a single ancestral gene in LUCA, so it is the confluence where those lineages meet, the way a cognate is shared across language branches. present in every cell; the physical implementation of the code the genomics stick seals. The homology is attested; the ancestral sequence is a reconstruction (a postulate, not sealed).
