TATA and CAAT are distinct patterns of nucleotides found in eukaryotes and archaebacteria. They are parts of two different consensus sequences and consequently parts of different promoter elements. The TATA box is located in the promoter region approximately 30 nucleotides from the initiation of transcription site. The CAAT box is located about 60-100 bases from the initiation of transcription site.
These two distinct nucleotide patterns are independent of each other, and they are located
