Abstract

A technique has been described for the isolation of intact mitochondrial polysomes which are active in protein synthesis. Mitochondrial ribosomes, derived from the polysomes, are of 71S particles and have 32S and 50S subunits. These subunits can initiate protein synthesis using mitochondrial RNA as a template. It is, thus, evident that mitochondria contain active messengers in the process of translation. The translational machinery in this organelle is prokaryotic in nature.
