| Abstract: | Temperature-sensitive mutations of human adenoviruses can be physically located on the viral genome by determining the DNA structures of recombinants formed in genetic crosses between different members of the same subgroup. We have analyzed the DNA structures of many interserotypic recombinants formed in crosses between temperature-sensitive (ts) mutants of adenovirus type 2 and adenovirus type 5 with the restriction endonucleases BamHI, EcoRI, HindIII, and and Sma I. In this way, we have mapped the physical coordinates of adenovirus type 2 (Ad2) ts1, Ad2 ts3, Ad2 ts4, and Ad2 ts48, and refined the mapping of Ad5 ts1. |
