Summary
Supercoiled infectious DNA was isolated from nuclear polyhedrosis virus infecting great wax moth (Galleria mellonella L.). Covalently closed DNA molecules constitute approximately 10–30 per cent in our preparations. These molecules dissappear during storage. Electron micrographs of supercoiled and open circular molecules are presented. Length of the open rings is about 50–52 µ. Infectivity of different DNA forms is discussed.
