For "box C/D snoRNAs, boxes C and D and an adjoining stem form a vital structure, known as the box C/D motif."[1]

In snoRNA U73 on the right, from the right side, the D box is AGUCY. In 5' to 3' direction, the D box is YCUGA.

Degenerate nucleotides

For transcription, U (in RNA) is T, Y=(C or T) and R=(A or G).

Consensus sequences

Shown in the image on the right is the D box (3'-AGUCUG-5'). Substituting T for U yields D box = 3'-AGTCTG-5' in the transcription direction on the template strand.

"Members of the box C/D snoRNA family, which are the subject of the present report, possess characteristic sequence elements known as box C (UGAUGA) and box D (GUCUGA)."[1]

Samplings

Regarding hypothesis 1

The D boxes are not involved in the transcription of A1BG.

For the Basic programs (starting with SuccessablesDbox.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 SuccessablesDbox--.bas, looking for 3'-AGTCTG-5', 1, 3'-AGTCTG-5', 2947,
  2. negative strand in the positive direction (from ZNF497 to A1BG) is SuccessablesDbox-+.bas, looking for 3'-AGTCTG-5', 1, 3'-AGTCTG-5', 3923,
  3. positive strand in the negative direction is SuccessablesDbox+-.bas, looking for 3'-AGTCTG-5', 1, 3'-AGTCTG-5', 1355,
  4. positive strand in the positive direction is SuccessablesDbox++.bas, looking for 3'-AGTCTG-5', 0,
  5. complement, negative strand, negative direction is SuccessablesDboxc--.bas, looking for 3'-TCAGAC-5', 1, 3'-TCAGAC-5', 1355,
  6. complement, negative strand, positive direction is SuccessablesDboxc-+.bas, looking for 3'-TCAGAC-5', 0,
  7. complement, positive strand, negative direction is SuccessablesDboxc+-.bas, looking for 3'-TCAGAC-5', 1, 3'-TCAGAC-5', 2947,
  8. complement, positive strand, positive direction is SuccessablesDboxc++.bas, looking for 3'-TCAGAC-5', 1, 3'-TCAGAC-5', 3923,
  9. inverse complement, negative strand, negative direction is SuccessablesDboxci--.bas, looking for 3'-CAGACT-5', 0,
  10. inverse complement, negative strand, positive direction is SuccessablesDboxci-+.bas, looking for 3'-CAGACT-5', 2, 3'-CAGACT-5', 1744, 3'-CAGACT-5', 2416,
  11. inverse complement, positive strand, negative direction is SuccessablesDboxci+-.bas, looking for 3'-CAGACT-5', 2, 3'-CAGACT-5', 15, 3'-CAGACT-5', 1616,
  12. inverse complement, positive strand, positive direction is SuccessablesDboxci++.bas, looking for 3'-CAGACT-5', 3, 3'-CAGACT-5', 2943, 3'-CAGACT-5', 3006, 3'-CAGACT-5', 3924,

  14. inverse, negative strand, positive direction, is SuccessablesDboxi-+.bas, looking for 3'-GTCTGA-5', 3, 3'-GTCTGA-5', 2943, 3'-GTCTGA-5', 3006, 3'-GTCTGA-5', 3924,
  15. inverse, positive strand, negative direction, is SuccessablesDboxi+-.bas, looking for 3'-GTCTGA-5', 0,
  16. inverse, positive strand, positive direction, is SuccessablesDboxi++.bas, looking for 3'-GTCTGA-5', 2, 3'-GTCTGA-5', 1744, 3'-GTCTGA-5', 2416.
