Abstract
In deoxyribonucleic acid of Rhizobium trifolii centrifuged in cesium chloride-ethidium bromide equilibrium was found a sattelite peak containing covalently closed circular deoxyribonucleic acid. The plasmid had a molecular weight of about 64 x 10(6) shown by sedimentation in sucrose gradients and electron microscopy.
摘要
在三叶草根瘤菌的脱氧核糖核酸中，经氯化铯-溴化乙锭平衡离心后，发现了一个含有共价闭合环状脱氧核糖核酸的卫星峰。通过蔗糖梯度沉降和电子显微镜观察，该质粒的分子量约为64×10⁶。
