DNA also has this sort of combinatorial system where you have a finite number of, I guess, bases or amino acids that could combine to a possible infinity of strings of DNA strings.

脱氧核糖核酸也拥有这种组合系统，你的生物基础或氨基酸数量是有限的，但却能组合出，几乎无限的脱氧核糖核酸螺旋结构。

The first step uses a bit of influenza DNA to get the patient's immune system to begin fighting off the flu, and then the protection is given a "boost" some time later by the second step, which can be either another bit of DNA or a conventional flu vaccine.

Interpol have already set up a prototype DNA database system which countries have only just started to add profiles to.

BBC: More than two million DNA samples are in the UK database

The paper estimates that each new profile added to the US DNA database - the Combined DNA Index System, or Codis - resulted in 0.57 fewer serious offences.
