The reactions are typically carried out on a regulated heating block, or PCR machine, and consist of 30-35 cycles of repeated amplification of all the DNA present.

这一反应通常是在一可调控的温箱中或PCR仪中进行，对所有的DNA进行30到35个循环扩增。

With nanopores, however, virtually no chemical pre-processing is required and no amplification. Instead a single strand of DNA can be read, one base pair at a time, and without the need for labelling.

但是如果用纳米孔，实质上就不需要化学与处理和“放大”，取而代之的是，可以一次一个碱基对地读出单条dna链，也不用标记。

Sequencing technology has come a long way since the Human Genome Project, but it still requires DNA to be copied millions of times, a step called amplification, and labelled with fluorescent tags.

测序技术在人类基因组计划后有了长足的进展，但是它仍然要求DNA经过一项称为“放大”的步骤，被复制几百万次，然后再用荧光标记。

It means that if, despite precautions, the Frankenbug does get out, its entirely harmless presence would be detectible in any given sample by straightforward DNA amplification technology of the sort used in genetic fingerprinting.

The new version puts the full DNA extraction, amplification and separation processes on a newer chip that meets NEC's original goal of producing output in 25 minutes -- faster than a short cop drama, if you include the commercial breaks.
