title: Hybridization of mitochondrial and cytoplasmic ribosomal RNA with mitochondrial and nuclear DNA.
abstract: Hybridization assays of rat liver mitochondrial and cytoplasmic rRNAs with in vitro labelled mitochondrial and nuclear DNA were performed in liquid medium. Sensitivity towards S1 enzyme and Tms of the RNA-DNA hybrids were studied. Our results are in favour of a distinct genetic origin of the two types of cellular rRNAs.
