Can pyrimidine dimers still anneal to a complimentary DNA strand?  For
example, can a T-T dimer anneal to A-A on a complimentary strand?
In our lab we do a lot of random-primed PCR at low annealing temps, and
therefore we see a lot of primer artifact (primer dimer, trimer, n-mer.)  I
am wondering if I can irradiate my primer to cause pyrimidine dimer formation
(and therefore render it ineffective as a template, reducing primer
artifact,) but still have it prime effectively.

Any thoughts/suggestions appreciated.
