COMMENTS

Explanation / justification of BP229 by its creator:
"Long (doubly sized) objects are purines (A & G).
Short objects are pyrimidines (C & T).
Black are those forming triple Hbond (G and C).
White are those forming double Hbond (A & T).
On the left we have matching codes, i.e., bases, doublets or triplets that, when rotated, can pair correctly (A with T, G with C), binding the two strands.
On the right we have objects that no matter how they are rotated they do not pair correctly (because of bumps, wrong color codes, etc)." |
