This diagram at the top here is a very familiar one to most of you, it's sometimes called the central dogma of molecular biology.

Some have even argued that there is an intuitive biology, a common-sense biological understanding of the world that's separate from your understanding of people and physics.
有些人甚至认为,大脑中存在着一个直觉生物学模块,这是一种与所具有的人类及物理学知识,并不相同的常识性生物学知识
But if you throw off the environment, in this case, the animal's biology, it's drive for certain nutrients is in concert with the food it has access to.

it's a two-and-a-half-year-long program that mixes biology, chemistry, physics and computer science together.
这门课是一个两年半的项目,涵盖了生物学、化学、物理学,还有计算机科学。
We'll talk about artificial organs and we'll talk about systems biology or thinking about how to acquire information for things like gene chips and use that information to understand what's happening in a complex organism like you.
我们会讨论到人造器官和系统生物学,并探讨如何从基因芯片中得到信息,并利用这些信息了解,人体作为一种复杂有机体的内在变化
So maybe you could figure out how to use what we know about molecular biology, to engineer a new virus that's still immunogenic, but not pathogenic any longer.
也许你能指出如何使用,分子生物学的有关知识,来设计一个既能产生免疫性,但又不再有致病性的新病毒
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.
这确实是分子生物学的一项利器,因为我可能只有,很少量的感兴趣的基因拷贝,而我可以马上制造出足够数量的复制品,能使我用作其他用途
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
That's a lot of what stem cell biology is like - is about.

In fact, even if you haven't had a biology class it's hard to be alive in 2008 and not know something about DNA; it's become such an important part of our lives.
实际上,即使你们没有上过生物课,也不可能活在当下却对DNA一无所知,它已经与我们的生活密不可分
That's why molecular biology, one of the reasons why it's turned out to be such a powerful tool, because if you can think creatively you can find all different ways to using these very simple principles to recombine molecules, to make unique new DNA sequences.
这就是分子生物学,如此有用的原因之一,因为如果你有创造力,你可以用各种方法,运用这些简单的原理来重组分子,创造独特的DNA新序列
