Abstract: | A restriction endonuclease cleavage map of bacteriophage T3 DNA has been constructed. The enzymes used and, within parentheses, the number of their cleavage sites on T3 DNA are: HindIII (1), XbaI (1), BglII (1), KpnI (2), MboI (9), and HpaI (17). The size and the relative location of each fragment have been established, defining an accurate physical map of T3 DNA. |
