Method Primary source abstract: "A DNA-dependent RNA polymerase has been purified to homogeneity from bacteriophage N4 virions. Sodium dodecyl sulfate-8 M urea polyacrylamide gel electrophoresis of the enzyme revealed a single polypeptide with a molecular weight of 350,000. The hydrodynamic properties of the enzyme have been determined to be 9.5 S for the sedimentation coefficient and 84 A for the Stokes radius."
Comments P.727 left column bottom paragraph: "The isometric head of N4 has a diameter of approximately 700 Å. A short, non-contractile tail is attached to the head [ref 15] The mature virion contains at least 10 gene products (gp) (Table 1) [primary source]. gp50, the vRNAP [DNA-dependent RNA polymerase], consists of 3500 amino acids and is present in the virion [primary source]."
