study of sedimentation coefficients of rat liver mt-rrnas labelled in vivo under conditions of selective inhibition by actinomycin d of nuclear rnas biosynthesis , in hypoosmic system of isolated mitochondria , and of mt-rrnas isolated from purified 55 ribosomes revealed that mt-rrnas are represented by 16s and 12s components .
