The genome complexities of different methanogenic bacteria were investigated by using an optical method to study renaturation kinetics of single-stranded DNA. The observed genome sizes ranged from 1.0 X 10(9) to 1.8 X 10(9) daltons, which is a typical range for procaryotic cells. Melting profiles of the DNA of three methanogenic species from different families show fractions which have a higher A . T content than the average DNA of that species.
通过使用光学方法研究单链DNA的复性动力学,对不同产甲烷菌的基因组复杂性进行了研究。观察到的基因组大小范围为1.0×10⁹至1.8×10⁹道尔顿,这是原核细胞的典型范围。来自不同科的三种产甲烷菌的DNA解链曲线显示,其部分片段的A.T含量高于该物种的平均DNA。
