What is the role of TATA box in transcriptional regulation?
May 2, 2016 · TATA box serves as a binding site for the TATA-binding protein (TBP; and its associated factors, together comprising the TFIID). TATA-box is one of the basic promoters present in many genes and therefore TBP is a general transcription factor i.e. TATA-box and TBP do not have specific roles. TATA-box is like a minimal promoter.
On which DNA strand is TATA box present? - Biology Stack Exchange
Dec 24, 2016 · In molecular biology, the TATA box (also called the Goldberg-Hogness box) [2] is a DNA sequence (cis-regulatory element) found in the promoter region of genes in archaea and eukaryotes. then TATA-box is merely a DNA sequence and is just a representation of a ssDNA region. However, TATA-box is also the binding site for TBP (TATA-binding protein ...
Solved TATA box coding region promoter RNA transcript The
TATA box coding region promoter RNA transcript The TATA box is an important sequence of DNA that is necessary for RNA polymerase to bind and start transcription. What specifically does the TATA box do? It binds RNA polymerase directly attaching it to the DNA.
The locations of the TATA box in two species of | Chegg.com
However, the TATA box of S. cerevisiae is 40 to 120 nucleotides upstream of the start site. To better understand what sets the start site in these organisms, researchers at Stanford University conducted a series of experiments to determine which components of the transcription apparatus of these two species could be interchanged (Y. Li et al. 1994.

molecular biology - Why don't housekeeping genes have TATA …
The TATA-box element (and notion of house-keeping genes) are classical textbook examples of trying to explain complex biology in a simplified manner. In fact, most mammalian genes do not have a TATA-box element and most transcription start sites (TSSs) are spread over a larger area in the 5' end of the gene.
Solved 14. The TATA box: O acts to position RNA polymerase
The TATA box: O acts to position RNA polymerase II for transcription initiation. o serves as a promoter sequence for genes transcribed by RNA polymerase III. O is present in all eukaryotic genes. O is located approximately 100 base pairs upstream of the start site for mRNAs.
