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.
Region of DNA that indicates to an enzyme where to bind to make rna?
The region of DNA that indicates where an enzyme should bind to initiate RNA synthesis is called the promoter sequence. The promoter sequence is typically located upstream of the gene that will be transcribed into RNA and is recognized by the enzyme RNA polymerase. Once bound to the promoter, RNA polymerase can begin the process of transcribing the gene into RNA.
When a negative transcription factor is added to the regulatory region of DNA, what happens?
DNA
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.
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.
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.
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.
A mutation in this section of DNA could influence the binding of RNA polymerase to the DNA?
A mutation in the promoter region of DNA, where RNA polymerase binds to initiate transcription, could influence the binding of RNA polymerase. This could alter gene expression by affecting the efficiency or ability of RNA polymerase to initiate transcription of the gene.
What is The nontranscribed region of DNA to which RNA polymerase binds to initiate transcription called?
The nontranscribed region of DNA to which RNA polymerase binds to initiate transcription is called the promoter region. It contains specific sequences that signal to RNA polymerase where to begin transcribing the gene.
What is the role of PCR primers in amplifying specific regions of DNA or RNA during the polymerase chain reaction process?
PCR primers are short pieces of DNA that bind to specific target sequences in the DNA or RNA being amplified. They serve as starting points for DNA polymerase to replicate the target region, allowing for the selective amplification of the desired DNA or RNA fragment during the polymerase chain reaction process.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
