The best way to label this DNA is by designing probes or labels that hybridize with specific sequences that you're interested in.

最好的标记方法是,设计出能与你感兴趣的,特定基因序列杂交的,分子探针或标签

These kinds of molecules which activate genes, they're activating the process of transcription.

这种分子能够激活基因,激活了转录过程

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

They're not whole genomes, but they're some small piece of DNA maybe the size of a protein.

不是整个基因组,而是小的DNA片段,但也许与蛋白质分子一样大

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

If you can interfere with any stage in RNA processing you can stop a gene from being expressed and this is a very hot topic in molecular biology now and human therapeutics.

如果你能干扰RNA加工的任何一个阶段,你就能阻止一段基因的表达,这也是当今分子生物学,和新型疗法中非常热门的话题
