title: Coding origin of isoaccepting tRNA in yeast mitochondria.
abstract: Valyl-, leucyl- and tyrosyl-tRNA of yeast mitochondria were fractionated by reversed phase chromatography. Each of the tRNA contained multiple isofunctional species. Some of them specifically hybridized to mitochondrial DNA from (see article) strain. These species were absent in a petite colonie mutant lacking mitochondrial DNA. Three valyl-, one leucyl- and one tyrosyl tRNA were found to be products of mitochondrial genes.
