今天查资料的时候，从阿简生物笔记里翻到的有意思的东东。 　　

　　貌似一家医疗仪器公司的广告。推销PCR仪器的广告。唱的应该是模仿We are the world吧。

　　歌曲最后一位老兄扛了台东西出来，一位是传真机，定眼再看，才认出是台PCR机器，实在是很impressive呀。。。想当年，老钟同学的毕业设计还是手动PCR技术呢，这几年的生物技术的发展真是日新月异呀。亲手做过分子试验的同僚们，看到这个video的话，是不是要唏嘘一下类？　

　　原文歌词如下。。

There was a time when to amplify DNA,
You had to grow tons and tons of tiny cells.

Then along came a guy named Dr. Kary Mullis,
Said you can amplify in vitro just as well.

Just mix your template with a buffer and some primers,
Nucleotides and polymerases, too.

Denaturing, annealing, and extending.
Well it's amazing what heating and cooling and heating will do.

PCR, when you need to detect mutations.
PCR, when you need to recombine.
PCR, when you need to find out who the daddy is.
PCR, when you need to solve a crime.

曾經有段日子，每當想要擴增DNA的時候
人們就必須養一大堆一大堆的小小細胞
然後出了個叫Kary Mullis博士的傢伙
他說其實在生物體外的試管中就可以做啦
只要把DNA模板跟緩衝液與引子混合起來
再加上核甘酸跟聚合酵素
變性、黏合、延長──
加熱降溫再加熱就能搞定的事還真是神奇！
當你需要偵測突變，跑個PCR吧!
當你想要重組DNA，跑個PCR吧!
當你想知道到底誰才是親生的阿爸，跑個PCR吧!
當你想要破解罪案的時候，跑個PCR吧!
