But what's amazing is that the hard drives we have today in a desktop or in a laptop, a hard drive and a laptop is only about--yey big!
现在你可能对在笔记本或者,台式机中存在的硬盘更感兴趣,其实硬盘仅仅是容量大了一些!
Here's something that may interest you.
这里有你们可能感兴趣的东西
So for some you that are less interested in maybe the physical structure of an individual atom, now some more exciting material for you might be coming up if you like to think about how, instead, molecules behave, either within bonding, within themselves, or with other molecules, that's what we're going to be heading to in this next unit.
那么对于某些同学,你们或许不感兴趣,对于单个原子的物理结构,现在可能有令你感到兴奋的内容,要出现了,如果你更喜欢思考,分子的行为,或者是关于成键的,或者是关于它们本身的,又或者与其它分子之间的行为,这些将是我们下个单元要讲的内容。
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
The answer is it will want to reform with itself, and if I have these in solution then how many reform with itself and how many reform with the molecule I'm interested probably depends on the relative concentrations of both in the solution and what conditions I have it at.
答案是质粒有可能会自己闭合,如果质粒和我感兴趣的DNA片段,都在溶液里那有多少质粒会自己合上,有多少与我感兴趣的DNA重组呢,这大概取决于两者在溶液里的相对浓度,和我让溶液处在什么条件下
