There are molecules in cells that give the DNA the signal that it's time to transcribe and express a gene, those are called transcription factors, we'll talk about them a bit later.

在细胞中有些分子能够,给DNA发出信号告诉它,是时候转录和表达某基因了,这些分子叫做转录因子,晚些时候我们会讲它们

We cannot say writing came into being belatedly with respect to speech in order to reproduce, imitate, or transcribe speech.

我们不能说书写比演讲产生得更晚,是为了复制，模仿，或者是记录下演讲的内容。

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
