title: Two human tyrosine tRNA genes contain introns.
abstract: A human lambda-phage recombinant which contains at least four tRNA genes, has been isolated. Two DNA fragments were subcloned to give the recombinant plasmids pM6 and pM6128. Nucleotide sequence analysis showed that each plasmid contained a different tyrosine acceptor tRNA (tRNATyr) gene. Both tRNATyr genes are interrupted by 21-bp introns. These recombinant plasmids have been shown to direct the in vitro synthesis of tRNA-sized products in a HeLa cell transcription system.
