Instead of Transcription Factors, what binds to RNA Polymerase to form a Complex to bind to the Promoter?
Sigma Factor Associates
Prokaryotic Termination occurs by what two mechanism?
- Rho-Dependent Terminators
- Rho-Independent Terminators
What do Rho-Dependent Terminators do?
They cause the Termination of Prokaryotic Transcription only in teh presence of Rho (protein)
What does Rho (protein) do in Prokaryotic Transcription?
Unwinds the DNA-RNA Hybrid
How do Rho-Independent Terminators work?
- The Terminator Sequence is Transcribed Before Transcription is Stopped.
- A Hairpin Structure forms that stop transcription along with a string of Uracil Nucleotides.
