Pollen and TCC regulatory element samplings
Copying the consensus for POLLEN1: 3'-AGAAA-5' and putting the sequence in "⌘F" finds many locations for this sequence in the A1BG directions as can be found by the computer programs. POLLEN1, AGAAA (−150/−146), has adjacent co-dependent regulatory element TCCACCATA (–141/–133), so that a combined consensus sequence expected would have AGAAANNNNTCCACCATA.
For the Basic programs testing consensus sequence AGAAANNNNTCCACCATA (starting with SuccessablesPol.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:
- negative strand, negative direction, looking for AGAAANNNNTCCACCATA, 0.
- positive strand, negative direction, looking for AGAAANNNNTCCACCATA, 0.
- positive strand, positive direction, looking for AGAAANNNNTCCACCATA, 0.
- negative strand, positive direction, looking for AGAAANNNNTCCACCATA, 0.
