WebJan 1, 2005 · The structure of eukaryotic promoters is generally more complex and they have several different sequence motifs, such as TATA box, INR box, BRE, CCAAT-box and GC-box ( 2 ). These sequence motifs were identified based on the analysis of a large number of promoters and they represent consensus sequences.
