This phenomenon is termed 'heter...Animals; Cell Line; Drug Resistance, Microbial; Fibroblasts; Mice; Models, Genetic; Neomycin; Plasmids1986-11-06
14 Capecchi, Mario R.Synthesis of an ochre suppressor tRNA gene and expression in mammalian cells.We have used site-specific mutagenesis to change the anticodon of a Xenopus laevis tyrosine tRNA gene so that it would recognize ochre codons.
