title: [Structure and biosynthetic functions of rat liver mitochondrial fractions].
abstract: Two mitochondrial fractions, dissimilar in their sedimentation characteristics, were isolated from rat liver homogenates using differential centrifugation. Morphological peculiarities of mitochondria of both these fractions, their capacity to protein and DNA synthesis as well as activities of several key enzymes of DNA biosynthesis were studied. The differences observed are discussed in terms of age dissimilarities of the mitochondria in the population.
