In my experience and from what I have seen around here, substructure
embedding for DNA/RNA is very tricky. The only thing to work seems
a full structure embedding (and here goes cpu!).
You could also consider ab initio or random simulated annealing (it's
in the X-PLOR manual).
The next release of X-PLOR should have torsion-angle dynamics which seems
to perform quite well for ab initio or random SA with DNA...
