Abstract
Electron microscopic analysis indicates that yeast nuclear DNA can be isolated as linear molecules ranging in size from 50 mum (1.2 x 10(8) daltons) to 355 mum (8.4 x 10(8) daltons). Analysis indicates the data is consistent with the hypothesis that each yeast chromosome contains a single, linear DNA duplex. Mitochondrial DNA molecules have a contour length of 21 +/- 2 mum and are mostly linear.
摘要
电子显微镜分析表明，酵母核DNA可以作为线性分子分离出来，其大小范围从50微米（1.2×10⁸道尔顿）到355微米（8.4×10⁸道尔顿）。分析表明，这些数据与每个酵母染色体包含一个单一的线性DNA双链体的假设一致。线粒体DNA分子的轮廓长度为21±2微米，且大多为线性。
