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.

摘要

酵母线粒体的缬氨酰 -、亮氨酰 - 和酪氨酰 - tRNA通过反相色谱法进行了分离。每种tRNA都包含多个同功异构体。其中一些与（见文章）菌株的线粒体DNA特异性杂交。在缺乏线粒体DNA的小菌落突变体中不存在这些异构体。发现三种缬氨酰 -、一种亮氨酰 - 和一种酪氨酰 - tRNA是线粒体基因的产物。
