Pausing occursat sequences rich in G/C base-pairs.
Difficult to disrupt stable G/C base-pairs to allow formationof the transcription bubble and to release RNA:DNA hybrid.
Pausing can last from 10 seconds to 30 minutes.
Two Major Mechanisms of Transcription Termination.
Rho protein terminates transcription by disruptingRNA:DNA hybrid and in an ATP dependent process migrates towardthe 3' end of the template, displacing the RNA polymerase anddisrupting the RNA:DNA hybrid.

Rho protein recognizes and binds to a specific RNAsequence in the template and then binds to approximately 80 additionalnucleotides of RNA at the pause site.
Inhibitors of Protein Synthesis in Eukaryotes:

RNA polymerase pauses at first G/C rich region, this allows thesecond G/C rich region of the RNA transcript to base-pair withthe first region- forming a RNA:RNA stem-loop duplex and eliminatingsome of the base-pairing between template and transcript.
