The DNA of adenovirus type 2 was cleaved by restriction endonuclease R.RI into six fragments. These fragments were separated by electrophoresis on composite agarose-polyacrylamide gels. Their molecular weights ranged from 1.1 x 10(6) to 13.6 x 10(6), as measured by electron microscopy. Each fragment represented a unique segment of adenovirus type 2 DNA since: (i) the fragments were obtained in equimolar amounts; (ii) the sum of their molecular weights was equal to the molecular weight of complete adenovirus DNA; and (iii) each fragment exhibited a rate of renaturation that was inversely proportional to its size.
2型腺病毒的DNA被限制性内切酶R.RI切割成六个片段。这些片段通过在复合琼脂糖-聚丙烯酰胺凝胶上进行电泳分离。通过电子显微镜测量,它们的分子量范围从1.1×10⁶到13.6×10⁶。每个片段代表2型腺病毒DNA的一个独特区段,因为:(i)片段以等摩尔量获得;(ii)它们分子量的总和等于完整腺病毒DNA的分子量;并且(iii)每个片段表现出的复性速率与其大小成反比。
