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.
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.
When a negative transcription factor is added to the regulatory region of DNA, what happens?
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.
Proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called?
Activators
Proeteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called?
inducer
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
A mutation in this section of DNA could influence the binding of RNA polymerase to the DNA?
promoter The promoter is the region of DNA to which RNA polymerase binds to in order to initiate transcription.
What enzyme binds to DNA and is responsible for making a transcript RNA of DNA?
RNA mRNA tRNA
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
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
What enzyme matches RNA nucleotides to complementary DNA nucleotides?
RNA polymerase
