How does bacterial RNA polymerase bind to the DNA during transcription?
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 is the region of DNA to which RNA polymerase bind?
promoter
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.
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.
Where does RNA polymerase bind?
RNA polymerase bind specific regions of DNA called promoters. The RNA polymerase holoenzyme is guided to promoters by interactions between members of the holoenyzme and specific DNA sequences such as the TATA box.
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.
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 are the proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter called?
transcription factor
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.
Why rna primer is used instead of dna primer?
There are basically two types of enzymes that can bind to DNA and copy it. The DNA polymerase and the RNA polymerase. The RNA polymerase, which copies DNA into RNA, will only bind to single stranded DNA, in other words areas of the DNA where the nitrogen bases holding the two strands of nucleotide units together have been separated. On the other hand the DNA polymerase that copies DNA into DNA will only bind to DNA that is double stranded. So in lies the dilemma. To make a copy of the DNA the DNA polymerase is use, but it will not bind to single stranded DNA so there is no way to make a DNA primer using aDNA polymerase, but the RNA polymerase will bind to single stranded DNA and there for can be used to make a small RNA primer on the open strands of DNA. Now the DNA polymerase has place that is double stranded and can attach and start copying the DNA.
What genetic locus serves as a recognition site for RNA polymerase?
The promoter region, typically located upstream of the coding sequence, serves as the recognition site for RNA polymerase. It contains specific DNA sequences that allow RNA polymerase to bind and initiate transcription.
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.
