This process allowed Sanger et al. to sequence the first genome, of a \(\varphi X174\) bacteriophage, in 19772. Although revolutionary, this method was costly, time consuming and labor intensive. Adjustments to this method were made in order to make it faster and less expensive. An important step was to change the way ddNTPs were marked. By using fluorescent markers, each base having a distinct “color”, we can eliminate the need to have 4 different environments and lanes in the gel35,36. This also paved the way for automating sequencing, each fluorescently marked band can be excited with a laser, and the resulting specific wavelength can be recorded by optical systems and the corresponding base automatically deduced37 (Also see Figure 1.3). Other improvements were made such as using capillary electrophoresis instead of gel electrophoresis.

这一幕，与罗马帝国后期近卫军操纵皇位的历史惊人相似。公元41年，近卫军在皇帝卡利古拉遇刺后擅自拥立克劳狄乌斯，首次展现了“造皇”能力。此后，由于帝国始终未能建立稳定且明确的继承制度，皇位传承长期在血缘继承、元老院推举与军队拥立等多种继承方式之间反复摇摆。
