For SerRS, the length of the variable arm is more crucial for its discrimination than sequence (Park and Schimmel, 1988; Asahara et al., 1993). 1 (1), 5968. The evolutionary histories of aminoacyl-tRNA synthetases (aaRS) are especially informative in detecting this signal, as they perform primordial biological functions, have undergone several ancient HGT events, and contain many sites with low substitution rates allowing deep phylogenetic reconstruction.

On the other hand, proteins were conclusively proved not to be the genetic material by Hersley and Chase in 1952 (Hershey and Chase, 1952), and the work by Rosaling Franklin, Maurice Wilkins, James Watson, and Francis Crick leading to the 1953 paper describing the three-dimensional structure of the genetic material DNA (Watson and Crick, 1953), and its double-helical structure with base-pairing according to Chargaffs rules (Chargaff, 1950). ; Goodrich, M.M. Clipboard, Search History, and several other advanced features are temporarily unavailable. The aaRSs and aaRS-interacting multi-functional proteins (AIMPs) are continually being implicated in tumorigenesis, but these connections are often limited in scope, focusing on specific aaRSs in distinct cancer subtypes. Specific interactions are mediated by identity elements such as modified nucleotides, conserved residues, base stacking, and different tRNA arm lengths. ; Chaikovsky, A.C.; Sage, J.; Howlett, C.J.
