WebRNA was isolated from cells with pFL38– rpb1ΔCTD at 30°C ( t = 0) or after 1 hr at 37°C ( t = 60) and hybridized to single-stranded M13 clones of fragments A or G (Fig. 1 D). As a control for recovery, 5S rRNA was also hybrid selected. Web7 jan. 1997 · In eukaryotes, RNA polymerase II transcribes messenger RNAs and several small nuclear RNAs. Like RNA polymerases I and III, polymerase II cannot act alone. Instead, general initiation factors [transcription factor (TF) IIB, TFIID, TFIIE, TFIIF, and TFIIH] assemble on promoter DNA with polymerase II, creating a large …
