Steve Ostro from the JPL recently asked me the following question:

I know that carbonaceous chondrites have been found to contain amino acids
used in proteins. Have any of the nitrogenous bases used in DNA been found
in any meteorites?

Shortly afterwards, he also provided me with the answer as well:

This question is answered in the Cronin et al. chapter in 
"Meteorites and the Early Solar System" 
(Kerridge and Matthews, eds.), U. Ariz series.

Adenine, guanine and uracil have been found.
