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 are enhancers in eukaryotes?
Sections of DNA which, when bound by particular proteins, increase transcription from a particular promoter. They can sometimes be many kilobases from the promoter in question.
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.
What are genes divided into?
The Divisions of the Gene are these: the Up - upstream enhancer sequences, the Upstream promoter sequences, the Operator Sequence that positions the Gene Polymerase Enzyme at the Start Codon, the Coding Sequence, and the Termination 'arrangement' [there are several Forms].
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.
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
Which is the protein involved in promoter recognition in eukaryotes?
TFIID
Which protein is involved in promoter recognition in eukaryotes?
Penis
Why does the promoter position differ between prokaryotes and eukaryotes?
In prokaryotes, the promoter is made up of two sequences at -10 and -35. Eukaryotic promoters are diverse and difficult to characterize, they lie upstream of the gene and have regulatory elements that are several kilobases away from the start site.
Can clones isolated from cDNA libraries contain promoter sequences?
C DNA library lack information about introns and regulatory sequences like promoter , enhancer etc.
What are enhancers in eukaryotes?
Sections of DNA which, when bound by particular proteins, increase transcription from a particular promoter. They can sometimes be many kilobases from the promoter in question.
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.
The TATA box in eukaryotes helps to ensure transcription true or false?
True, the TATA box helps ensure transcription in prokaryotes and eukaryotes. It is found in the promoter region of genes.
Where in the promoter do transcription factors bind?
Completely Specific Transcription Factors bind to equally specific Dna Sequences that are located and found within The Promoter [Dna] Sequence. Up-Stream from the promoter sequence are the enhancer sequences; Down-Stream is the Operator Sequence - followed by the encoded information.
What is an UP element in DNA?
The UP element is a region upstream the promoter that also stimulates transcription through a direct interaction with the C-terminal domain of the RNA polymerase subunit (CTD). Then, UP element is a promoter element.
What are genes divided into?
The Divisions of the Gene are these: the Up - upstream enhancer sequences, the Upstream promoter sequences, the Operator Sequence that positions the Gene Polymerase Enzyme at the Start Codon, the Coding Sequence, and the Termination 'arrangement' [there are several Forms].
What has the author Chris Claxton written?
Chris Claxton has written: 'Examination of the CIS-elements of the rat endothelin type a promoter'
