Tata box

The TATA box is the 5' TATA 3' sequence which is found in the DNA strand of a promoter. The TATA box is usually found near the -10 region of the promoter. The TATA box is a common promoter sequence reconised by RNA Polymerase II. It is found in both prokaryotes and eukaryotes however in the two it's spacing from the transcriptional start site differs.
