It's really been a powerful tool in molecular biology because I might have a very small copy of a gene that I'm interested in and I can make enough copies that I can start to do something else with it.

-
When transcription happens and it turns out that there's a whole biology associated with this, including molecules that are floating around inside your cells called transcription factors, and their job-- they are molecules that are about particular genes and what some of the sequences and are able to turn on those genes inside cells, to make them transcribe.
研究证明,当细胞转录时,还有与之相关的一整套生物机制在运作,包括一种在你细胞中飘浮着的,称为转录因子的分子,它们的工作就是,它们知道该转录哪一段基因,该转录哪一段序列,然后把这些细胞中的基因激活,进行转录
