Abstract
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 micron. Infectivity of different DNA forms is discussed.
摘要
从感染大蜡螟（Galleria mellonella L.）的核型多角体病毒中分离出超螺旋感染性DNA。在我们的制备物中，共价闭合的DNA分子约占10%-30%。这些分子在储存过程中消失。文中给出了超螺旋分子和开环分子的电子显微镜照片。开环的长度约为50-52微米。文中还讨论了不同DNA形式的感染性。
