TAGteam samplings

Copying the consensus TAGteam: CAGGTAG and putting the sequence in "⌘F" finds one location between ZNF497 and A1BG or no locations between ZSCAN22 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence CAGGTAG (starting with SuccessablesTAG.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 CAGGTAG, 0.
  2. positive strand, negative direction, looking for CAGGTAG, 0.
  3. positive strand, positive direction, looking for CAGGTAG, 0.
  4. negative strand, positive direction, looking for CAGGTAG, 1, CAGGTAG at 4035.
  5. complement, negative strand, negative direction, looking for GTCCATC, 0.
  6. complement, positive strand, negative direction, looking for GTCCATC, 0.
  7. complement, positive strand, positive direction, looking for GTCCATC, 1, GTCCATC at 4035.
  8. complement, negative strand, positive direction, looking for GTCCATC, 0.
  9. inverse complement, negative strand, negative direction, looking for CTACCTG, 0.
  10. inverse complement, positive strand, negative direction, looking for CTACCTG, 0.
  11. inverse complement, positive strand, positive direction, looking for CTACCTG, 0.
  12. inverse complement, negative strand, positive direction, looking for CTACCTG, 1, CTACCTG at 1198.
  13. inverse negative strand, negative direction, looking for GATGGAC, 0.
  14. inverse positive strand, negative direction, looking for GATGGAC, 0.
  15. inverse positive strand, positive direction, looking for GATGGAC, 1, GATGGAC at 1198.
  16. inverse negative strand, positive direction, looking for GATGGAC, 0.

Comparison:

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