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.

Proteins that bind to DNA and turn on operons by making it easier for RNA polymerase to bind to a promoter are called?
Activators
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 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
What are the different types of RNA polymerases and their promoters?
rma polymerase 1, rna polymerase 2, rna polymerase 3
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What does bacterial rna polymerase bind to?
promoter
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?
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 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.
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
What enzyme binds to DNA and is responsible for making a transcript RNA of DNA?
RNA mRNA tRNA
What are the different types of RNA polymerases and their promoters?
rma polymerase 1, rna polymerase 2, rna polymerase 3
When a negative transcription factor is added to the regulatory region of DNA, what happens?
DNA
