Answer:
DNA polymerases and aminoacyl-tRNA synthetases (ARSs) represent large enzyme families with critical roles in the transformation of genetic information from DNA to RNA to protein.
Explanation:
Aminoacyl-tRNA synthetases (aaRS) play a central role in protein biosynthesis by catalyzing the attachment of a given amino acid to the 3' end of its cognate tRNA. They do this by forming an energy-rich aminoacyl-adenylate intermediate of the cognate amino acid, which serves to transfer the amino acid to the tRNA.
