A different sequencing method that chemically cleaved DNA at specific bases, developed by Allan Maxam and Walter Gilbert, was the dominant technology into the 1980s. Radiolabeled DNA samples were incubated in four separate reactions, each of which contained a chemical that cleaved after a different nucleotide — either A/G, G, C, or C/T. By adding the right amount of each chemical, it was possible to produce different fragments chopped off at each individual base. The sequence could then be read using gel electrophoresis and autoradiography. Maxam–Gilbert sequencing was easier than the plus and minus method to run and interpret, but was eventually surpassed by Sanger’s chain termination method, which molecular biologists found both technically preferable and more “elegant” since it mirrored the natural copying of DNA.

It was a particularly heinous crime. Four workers at a cemetery near Chicago dug up more than 100 bodies and dumped the remains elsewhere in the grounds, in order to resell the burial plots for profit.

More importantly, the subjective difference is obvious. The conversation feels responsive. Interruptions work cleanly. The agent no longer feels like it’s hesitating before every reply.，这一点在体育直播中也有详细论述
