"Although the first five bases of the conserved sequence are identical to the first five bases of the Pribnow box (TATAA), the sixth base of the Pribnow box is a 100 per cent conserved T (refs 15-17) while the 100 per cent conserved A found here is actually more similar to eukaryotic promoter sequences20."[1]

"Two domains upstream of the start site of transcription have been identified for which a consensus sequence has been formulated(1-5). These domains are the -35 sequence (5'-T-T-G-A-C-A) and the Pribnow box (5'-T-A-T-A-A-T) in the -10 region. Both domains are in close contact with the RNA polymerase during initiation of RNAsynthesis (2,6)."[2]

Samplings edit

For the Basic programs (starting with SuccessablesPrib.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:

  1. negative strand in the negative direction (from ZSCAN22 to A1BG) is SuccessablesPrib--.bas, looking for 3'-TATAAT-5', 2, 3'-TATAAT-5', 3454, 3'-TATAAT-5', 3468,
  2. negative strand in the positive direction (from ZNF497 to A1BG) is SuccessablesPrib-+.bas, looking for 3'-TATAAT-5', 1, 3'-TATAAT-5', 729,
