Two new species of cytoplasmic RNA with approximate sedimentation values of 12S and 21S, and which appear associated with mitochondria, are described. The species are unmethylated, are relatively metabolically stable, and have a 43 per cent G + C content. Their synthesis is uniquely resistant to inhibition by UV irradiation. The 12S and 21S RNA do not appear to be components of polysome-like structures.
本文描述了两种新的细胞质RNA,其沉降系数约为12S和21S,似乎与线粒体有关。这两种RNA未甲基化,代谢相对稳定,鸟嘌呤与胞嘧啶的含量为43%。它们的合成对紫外线照射具有独特的抗性。12S和21S RNA似乎不是多聚核糖体样结构的组成成分。
