Segment of an unknown target DNA sequence. DNA segments were modeled with the following logic: vrRNA NN domains were modeled as adenosines or cytosines, the target strand was modeled as complementary to the vrRNA with x3 bases being treated as cytosines or guanines as density permitted. The non-target strand was modeled largely as thymines, with intermittent guanines and cytosines as density permitted.
