Abstract:
A bovine genomic clone containing a 17.4-kb DNA fragment was isolated and found to contain a solitary arginine tRNA gene with an anticodon of CCG that has a 100% identity to its cognate tRNA. This arginine tRNA gene, symbolized as TRR4, has a characteristic internal split promoter and a typical termination site for RNA polymerase III. The tRNA gene was transcribed in vitro by RNA polymerase III using a HeLa cell-free extract to yield a mature-sized tRNA product. The gene was mapped to bovine chromosome 19 using a panel of bovine-rodent somatic cell hybrid DNAs.
