PROCESS OF INFECTION WITH COLIPHAGE T7 .1. CHARACTERIZATION OF T7 RNA BY POLYACRYLAMIDE GEL ELECTROPHORETIC ANALYSIS

Twelve T7 RNA species can be identified by electrophoresis in polyacrylamide gels. The sum of the molecular weights of the species is sufficient to account for the entire genome of T7. Some of the large species must certainly be polycistronic in nature. All identifiable T7 species are represented in infected cells prior to the onset of DNA synthesis. © 1969.
