TACTAAC box gene transcriptions
"A consensus sequence TACTAA(C/T) was derived for the branch site of Dictyostelium introns."

# Consensus sequences
"The comparison of the two rp51 genes  suggests that this homology might be more extensive if one allows up to 3 bases to differ from a larger consensus sequence, ATTTACTAAC."

# TACT samplings
For the Basic programs (starting with SuccessablesTACT.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 in the negative direction (from ZSCAN22 to A1BG) is SuccessablesTACT--.bas, looking for TACTAA(C/T), 0,
- negative strand in the positive direction (from ZNF497 to A1BG) is SuccessablesTACT-+.bas, looking for TACTAA(C/T), 0,
- positive strand in the negative direction is SuccessablesTACT+-.bas, looking for TACTAA(C/T), 0,
- positive strand in the positive direction is SuccessablesTACT++.bas, looking for TACTAA(C/T), 1, TACTAAT at 4157,
- inverse complement, negative strand, negative direction is SuccessablesTACTci--.bas, looking for (A/G)TTAGTA, 0,
- inverse complement, negative strand, positive direction is SuccessablesTACTci-+.bas, looking for (A/G)TTAGTA, 0,
- inverse complement, positive strand, negative direction is SuccessablesTACTci+-.bas, looking for (A/G)TTAGTA, 0,
- inverse complement, positive strand, positive direction is SuccessablesTACTci++.bas, looking for (A/G)TTAGTA, 1, ATTAGTA at 4148,

# TACT analysis and results
"A consensus sequence TACTAA(C/T) was derived for the branch site of Dictyostelium introns."
Comparison:
The occurrences of real TACTs are greater than the randoms. This suggests that the real TACTs are likely active or activable.
