Bacterial RNA polymerase binds to DNA during transcription by recognizing and binding to specific DNA sequences called promoters. The polymerase enzyme then unwinds the DNA double helix and begins synthesizing a complementary RNA strand using one of the DNA strands as a template.
What else can I help you with?
Does RNA polymerase bind to the TATA box during transcription initiation?
Yes, RNA polymerase binds to the TATA box during transcription initiation in eukaryotic cells.
Where does RNA polymerase bind to the DNA to initiate transcription?
RNA polymerase binds to the DNA at a specific region called the promoter to initiate transcription.
What is the role of the sigma factor in transcription?
The sigma factor is a protein that helps RNA polymerase bind to the promoter region of a gene during transcription. It plays a crucial role in initiating the process of transcription by guiding RNA polymerase to the correct starting point on the DNA strand.
Proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called?
Transcription factors are proteins that bind to DNA and help regulate the initiation of transcription by RNA polymerase at promoter regions. They can enhance the binding of RNA polymerase to the promoter, thereby turning on the expression of specific operons.
Why doesn't RNA polymerase require a primer for transcription?
RNA polymerase does not require a primer for transcription because it can initiate the process on its own by recognizing specific DNA sequences called promoters. This allows RNA polymerase to bind to the DNA and start synthesizing RNA without the need for a primer like DNA polymerase does during DNA replication.
Does RNA polymerase bind to the TATA box during transcription initiation?
Yes, RNA polymerase binds to the TATA box during transcription initiation in eukaryotic cells.
What does bacterial rna polymerase bind to?
promoter

What are a group of proteins that bind to the promoter or enhancer sequences to facilitate the binding of RNA polymerase to the promoter?
Transcription factors are proteins that bind to promoter or enhancer sequences to help recruit RNA polymerase to the promoter. They regulate the transcription of specific genes by promoting or inhibiting the binding of RNA polymerase to the DNA.

Proeteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called?
Transcription factors.
When a negative transcription factor is added to the regulatory region of DNA, what happens?
DNA
Are promoters signals in RNA that indicate RNA polymerase when to begin transcription?
Yes, promoters are specific sequences in DNA that signal RNA polymerase where to bind and start transcription of a gene into RNA. Promoters contain regions recognized by RNA polymerase, which initiate the transcription process.
What is the function of sigma factor in transcription?
when RNA Polymerase meet the correct promoter(TATA box), it will bind at that region and then sigma factor will also bind to the RNA Polymerase.once ATP give energy, sigma factor will dissoiates from RNA Polymerase and the enzyme start to unwind the double helix
