Specific DNA Restriction Fragments as Internal Markers in the Electron Microscope: Superimposing the ɸX174 Genetic Map on ɸX174/S13 DNA Heteroduplexes
<p>Chapter I</p> <p>ɸX174 RF II* molecules were constructed in vitro by annealing circular ɸX174 viral DNA and linear ɸX174 complementary strand DNA. When a specific fragment of ɸX174 RF purified from a digestion with the restriction endonuclease Hind from Hemophilus influenzae...
