Abstract
Target analyses of the induction of rho(-) mutants indicated that the cytoplasm of an aerobic nonrepressed yeast contains approximately 20 mutable units, whereas repressed cells exhibit approximately 3. Aerobic adaptation of fully repressed cells brings about an increase in these cytoplasmic units which continues after maximal respiration has been reached. This increase can be correlated with the increase in numbers of stained mitochondria. The data are interpreted with reference to mitochondrial deoxyribonucleic acid.
摘要
对rho(-)突变体诱导的靶向分析表明，需氧非阻遏酵母的细胞质中约含有20个可变单位，而阻遏细胞约有3个。完全阻遏细胞的需氧适应会使这些细胞质单位增加，在达到最大呼吸后这种增加仍会持续。这种增加与染色线粒体数量的增加相关。数据参照线粒体脱氧核糖核酸进行了解释。
