Characterization of the DNA of the Nuclear Polyhedrosis Virus of the Cotton Bollworm, Heliothis zea

Abstract
The circular DNA molecules of cotton bollworm nuclear polyhedrosis virus, visualized by EM, have a MW of 81 .times. 106. Renaturation kinetics studies suggest a genetic complexity corresponding to a MW of 82 .times. 106. A G + C content of 42% for the virus DNA is estimated from its thermal denaturation profile and buoyant density in CsCl.
