Rare amount of DNA sample often needs repeated amplification in order to remain enough amount of DNA template for various analysis.

基因操作者经常需要把数量稀少的DNA样品进行反复扩增以供进一步研究之用。

Influenza virus sample in cultured cells was treated for reverse transcription, amplification, fluorescent dye labelling, hybridization and scanning.

对待检样品进行随机逆转录和扩增，荧光标记，杂交， 扫描分析。

Sample preparation does not require ligation or PCR amplification, avoiding the GC-content and size biases observed in other technologies.

样本准备不需要延伸或PCR扩增，避免了在其他技术中观测到的GC含量及大小偏差。

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.
