[Characteristics of poly A-containing RNA from liver mitochondria of normal and adrenalectomized rats].

Mitochondrial poly(A)-containing RNAs from the liver of normal and adrenalectomized rats were analyzed electrophoretically in agarose gel with urea. It was revealed that after the glucocorticoid hormone level descended, the content of a single high-molecular poly(A)-containing RNA in liver mitochondria was significantly lowered. This RNA is mapped on mitochondrial DNA as RNA 5 by the blotting-hybridization method (according to the classification of Amalric et al., 1971).
