Abstract
The synthesis of full-length complementary DNA copies of avian myeloblastosis virus RNA is described. The cDNA is estimated by electrophoresis in agarose-methylmercury gels to have a molecular weight of 2.6 X 10(6), equivalent in size to that of the RNA template. Most (60-70%) of the reaction product is the full-length material and yields correspond to 60-70% of the input RNA.
