The TATA box seems to help position RNA polymerase by marking a point just before the point at which transcription begins.

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.
What is the function of the TATA box?
The TATA box assists in directing RNA polymerase II to the initiation site downstream on DNA. RNA polymerases bind to regions of DNA known as promoters. Promoter regions are comprised of the initiation site and numerous nucleotides upstream from the initiation site. The TATA box is necessary for transcription because RNA polymersase II cannot recognize the initiation sites on its own.
What is the region where RNA polymerase binds on DNA?
The transcription initiation complex around the TATA box.
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.
What does Transcription in eukaryotes require in addition to RNA polymerase?
General Transcription Factors (GTF). TFIID (binds to DNA first at TATA box), TFIIA, TFIIB, TFIIF, TFIIE and TFIIH.

Who was the second chairman of tcs after jrd tata?
J.R.D. Tata held the chairman position from 1938 to 1991 after that the position was held by Ratan Tata from 1991 to 2012. The position is now held by Cyrus ministry.
Difference between pribnow box and hogness box?
A SH=hort nucleotid esequence in the promoter 25 to 35 bp upstream to the transcription initiation site of eukaryotic genes to which polymerase binds is called TATA BOX. IT IS CALLED AS PRIBNO BOX IN CASE OF PROKARYOTES and called as HOGNESS BOX in case of EUKARYOTES.. It has conserved squence of tataata (I am a ifferent person) As far as I know, TATA box is located only in eukaryotic genes and genes of archae. It is on -25 position from the transcription initiation site. Also, it is TATAAA sequence with small variations (more A can be added). It's also called Goldberg-Hogness box. In contrast, in prokaryots, this sequence is called Pribnow box. Its location is at -10. It consists of TATAAT sequence with small variations.
What is initiation in transcription?
So in Transcription there are three main steps: Initiation, elongation and termination. The one I'm focusing on is Initiation. In eukaryote, proteins called transcription factors mediate the initiation of transcription by RNA Polymerse II. A eukaryotic promoter commonly includes a TATA box, a nucleotide sequence containing "Thymine-Adenine-thymine-adenine", about 25 nucleotides upstream from the transcriptional start point.
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.

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
The correct order for the assembly of the eukaryotic transcription complex is?
Transcription factors bind in this order: D, A, B, F, E, H, J.RNA polymerase (usually RNA pol II for transcription fo protein coding genese) binds with TFIIF.DetailsInitially, TFIID binds to the TATA box of the DNA strand, if present, since the TBP is part of the TFIID complex. The shape of TBP causes large changes in the shape of the DNA molecule, unwinding it greatly. This allows TFIIA and then TFIIB (with TFIID) to bind to the promoter region, followed by TFIIF (similar to sigma factor in prokaryotes) with RNA polymerase II, then TFIIE, which enables the polymerase to move along the DNA easily, and TFIIH, which contains a helicase to unwind the DNA and an enzyme region to phosphorylate (initiating elongation) a region of the polymerase II enzyme known as the C terminal domain (which is unique to this form of polymerase II). This forms a complex known as the basal transcription apparatusOther transcription factors may also bind depending on the specific gene being transcribed. TBP binds specifically to the TATA box, and in the case of the large number of genes that do not use the TATA consensus sequence this will be replaced by that gene's alternative.For further information on the structure of the completed complex, I recommend the structure of the RNA polymerase II elongation complex to 3.3 angstroms as determined by Gnatt et al.
Why the first porting complex bind to TARA box?
The TATA box (also called Goldberg-Hogness box) is a DNA sequence. The polymerase can then recognize this multi-protein complex and bind to it.
