Consensus sequences

The consensus sequence for the TAPETUM box is TCGTGT.

Tapetum box samplings

Copying the consensus Tapetum box: TCGTGT and putting the sequence in "⌘F" finds one location between ZNF497 and A1BG and one between ZSCAN22 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence TCGTGT (starting with SuccessablesTAP.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, negative direction, looking for TCGTGT, 1, TCGTGT at 3915.
2. positive strand, negative direction, looking for TCGTGT, 0.
3. positive strand, positive direction, looking for TCGTGT, 1, TCGTGT at 3740.
4. negative strand, positive direction, looking for TCGTGT, 1, TCGTGT at 80.
5. complement, negative strand, negative direction, looking for AGCACA, 0.
6. complement, positive strand, negative direction, looking for AGCACA, 1, AGCACA at 3915.

Comparison:

The occurrences of real TAPs are greater than the randoms. This suggests that the real TAPs are likely active or activable.
