A promoter is a sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it. A promoter is usually referred to as a "TATA (thymine, adenine, thymine, adenine) box" or a "CAAT (cytosine, adenine, adenine, thymine) box". As DNA polymerase makes its way down a section of DNA and comes across TATA box, or a CAAT box, that is the signal to begin transcription.
What else can I help you with?
What is the region of DNA where RNA synthesis begins called?
The region of DNA where RNA synthesis begins is the promoter. DNA contains a number of upstream regulatory and promoter sequences but the region of DNA where RNA synthesis begins is the start codon. This is the first codon that translates into an RNA nucleotide.
Where does transcription take place in DNA?
DNA transcription occurs in the nucleus. It begins at a site known as the promoter, and continues along the DNA template strand that is being transcribed. answer: Nucleus. But to be more exact, promoter.
What is the sequence of nucleotides on DNa to with ran polymerase will attach to start transcription?
A promoter is a segment of DNA that helps RNA polymerase recognize the start of a gene.
What is the functional difference between enhancers and promoter proximal elements?
Enhancers are at considerable distances from the promoter and can be moved or inverted and still function. Promoter-proximal elements are close to the promoter and their position and orientation must be maintained.
In eukaryotes the interaction of enhancer and promoter elements is brought closer by?
In eukaryotes, the interaction of enhancer and promoter elements is brought closer by the bending of DNA. Proteins called transcription factors bind to enhancer elements and recruit complexes that help bend and loop the DNA, bringing the enhancer and promoter regions into close proximity for efficient gene expression.
What is the region of DNA where RNA synthesis begins called?
The region of DNA where RNA synthesis begins is the promoter. DNA contains a number of upstream regulatory and promoter sequences but the region of DNA where RNA synthesis begins is the start codon. This is the first codon that translates into an RNA nucleotide.
Where does transcription start in a prokaryotic promoter?
Transcription in a prokaryotic promoter starts at the DNA sequence called the "promoter region."
What process begins at the promoter of DNA?
The promoter is the sight at which the transcription machinery binds the DNA and initiates the transcription of the gene.
What is a DNA promoters?
A Promoter is a region of DNA that facilitates the transcription of a particular gene.
What characterises a cancer promoter?
A cancer promoter causes cells with DNA mutations to multiply and become tumors.
What is the region of DNA to which RNA polymerase bind?
promoter
What a enzyme?
Its involved in promoter specifictiy in DNA transcription
Where does transcription take place in DNA?
DNA transcription occurs in the nucleus. It begins at a site known as the promoter, and continues along the DNA template strand that is being transcribed. answer: Nucleus. But to be more exact, promoter.
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.
Transcription starts at a region of DNA called a?
According to biologists, transcription starts at a region of DNA called a promoter. Promoters bind with RNA molecules to initiate transcription.
Is DNA junk or not junk?
AnswerThere is junk DNA or non-coding DNA. This DNA is the segment before the promoter of a different gene.
What is a halo-enzyme?
Its involved in promoter specifictiy in DNA transcription
