78 – Découpage des ARN ribosomiques d’Escherichia coli par la ribonucléase U2 et transcription in vitro des “ARN-fragments” en ADN complémentaire

C.R. Acad. Sci., 1978, 286, pp. 1825-1828 (série D). Available in French only 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.Voir le document
