Abstract: | RIBOSOME-BOUND, low molecular weight RNA, distinct from tRNA, was first observed in E. coli by Rosset and Monier1. This RNA, which has a sedimentation coefficient of about 5S, is now considered to be a universal component of ribosomes. We report here our attempts to find low molecular weight RNAs other than tRNA in mitochondria of Neurospora. Our evidence suggests that the mitochondrial ribosomes of this organism lack a 5S RNA component. |
