• When RNA is copied, one strand acts as a template, and a replicase ribozyme would accurately guide which letters are added to the strand under construction. (elifesciences.org)
  • These results suggest that the RNA viruses do not employ DNA as an in- formational component at any step unique to the production of mature virus particles. (nih.gov)
  • Ribonucleic acid preparation and purification: All RNA preparations, from either mature phage or cell lysate, were purified by the phenol procedure. (nih.gov)
  • Their formation can therefore be adequately explained in terms of the DNA-dependent RNA poly- merase. (nih.gov)
  • This conclusion is further strengthened by the observation that acti- nomycin D inhibits normal cellular RNA synthesis but is unable to interfere with viral RNA formation. (nih.gov)
  • In the third phase, the structural and regulatory components necessary for the formation of the hyphal form are produced. (dadospdf.com)
