Rho Independent Termination Transcription in Prokaryotes ...
WebJul 3, 2024 · The first step in intrinsic termination is transcription pausing at the end of the T/U tract. This pause provides time for the terminator hairpin to form in the RNAP exit channel, which disrupts RNAP-nucleic acid interactions that stabilize the EC and causes 3 to 4 bp of the upstream RNA-DNA hybrid to melt.
