i think it is only in eukaryotes
True, the TATA box helps ensure transcription in prokaryotes and eukaryotes. It is found in the promoter region of genes.
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.
General Transcription Factors (GTF). TFIID (binds to DNA first at TATA box), TFIIA, TFIIB, TFIIF, TFIIE and TFIIH.
The transcription initiation complex around the TATA box.
The TATA box seems to help position RNA polymerase by marking a point just before the point at which transcription begins.

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.
yes, the TATA box (and broader idea, the promoter) is sequence read on the sense (non-template) strand for convention.

TFIID recognizes the TATA box.
The transcription initiation complex around the TATA 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.
The TATA box seems to help position RNA polymerase by marking a point just before the point at which transcription begins.
Jack-in-the-Box is a toy found in the toy box. Jacks are found in the toy box.
i have a 42 in monitor with hdmi but no coax cable or tv tuner card can i get a converter box or cord or can i instal or get a box with a tv tuner card
