TBP binds a cis-acting element within this sequence. What is the coordinate of the 5’ deoxynucleotide of this cis-acting element?
TBP = TATA binding protein.
It is a general transcription factor that binds to the TATA box +30
base upstream to the transcription start site.
TATA box consencus sequence: 5'-TATA(A/T)A(A/T)-3'
