Many kinds of molecules make up your coffee There are the water molecules, the flavor molecules the milk proteins, etcetera.
许多不同种类的分子构成了你的咖啡,有水分子,气味分子,牛奶蛋白等等。
So now, for example, there are a whole range, just a whole rainbow of fluorescent proteins that can be used.
现在,人们可以用的荧光范围,达到整个彩虹色谱。
Another example of using this technique is to produce therapeutic proteins from cloned DNA and I'm going to describe this one.
另一个运用到此技术的例子就是,从克隆的基因中制造治疗性的蛋白质,我会具体说这个例子
We are now able to find proteins and genes that are at the correct location for the transduction machinery.
我们就能够查明转导蛋白质和基因,处于正确的位置。
Because of this, they can't repair the various kinds of damage they need, or create the amino acids and proteins they need.
他们不能修复各种损伤,或者生成所需的氨基酸蛋白质
These proteins have functions that are essential for life of the cell, they transport molecules back and forth across the membrane.
这些蛋白所起的功能,对于细胞生存至关重要,它们负责转运分子通过细胞膜进出细胞
Steroids are small molecules - much smaller than proteins - smaller molecules that tend to be hydrophobic or lipid soluble.
类固醇是小分子物质,比蛋白质小得多,这类小分子是非水溶性的,或者说是脂溶性的
That's one of the beauties of proteins as working molecules is that their structure can be changed by subtle means.
蛋白质作为一种生物活性分子,其优势之一是,能够通过精细的方法改变其结构
If I could find the unique set of proteins that correspond to those genes I could define chemically what the cell is.
而我又能找到和这些基因对应的,这种独特的蛋白,我就能通过化学手段确认这是哪种细胞
You could watch where it localizes in the cell, there are fluorescent assays you could use to determine what other proteins it interacts with.
你可以看到它在细胞的什么地方,你可以用荧光化验的办法确定,它和其它什么蛋白质相作用。
There are proteins, for example, on the surface of some cells that bind insulin and respond to the presence of insulin.
比如说蛋白,有些细胞表面上的蛋白,捕获胰岛素并且对胰岛素进行应答
It leads to expression of new genes, production of new proteins, and a change in a behavior of the cell.
这导致新基因表达,新蛋白合成,细胞行为发生改变
When this animal makes milk, it makes all the normal milk proteins, but it also activates your gene of interest as well.
那么当这一后代泌乳的时候,它不仅表达出自身正常的奶蛋白质,也激活了目的基因的表达
Some chemical concepts that are important for us to all understand as we move forward and review of proteins and biochemistry, basically.
随着课程的深入,其中的一些概念,对我们全面理解课程内容至关重要
Maybe it got mutated and its making the wrong kinds of proteins; cancer cells often do that.
它可能已经变异,产生了错误的蛋白,癌细胞往往就是这样
