There are 27 of these repeats in the yeast Pol II CTD, 32 in the worm Caenorhabditis elegans, 45 in the fly Drosophila, and 52 in humans. 

YSPTSPS repeats in CTD corresponds to the complexity of the genome.

Start point, is the first base of mRNA to be A

• Initiator (Inr) is Py2CAPy5, where Py stands for any pyrimidine. The Inr is contained between positions -3 and +5.

• TATA box, usually located, 25 bp upstream in its location at -25

• The exception is in yeast, where the TATA box is more typically found at -90.
