ABSTRACT: Under well defined conditions ribosomal RNAs purified from Escherichia coli can be degraded by ribonuclease U2 giving rise to RNA fragments of 60-70 nucleotides. In vitro, these fragments are efficently transcribed into a complementary DNA by DNA polymerase RNA dependent, partially purified from extracts of E. coli. In vivo, “RNA-fragments-U2” inhibit the development of plant tumors.
