In general, good programming style says you put in comments that are going to be valuable in helping you as a reader understand what's going on inside of the code.
通常来说，优秀的编码风格意味着,你要放进去的注释,在帮助代码阅读者,理解代码内部,是怎么工作的。
-
But yeah, there is some code, you know a lot of, sometimes cross browser issues
但事实上，也有些编码，你知道很多跨浏览器的问题，
-
Last time we used printf generally to print a static string, like a hardcoded string, like "David," just for example's sake.
上次我们通常用“printf“,来打印一个静态的字符串，像硬编码的字符串“David“,这只是个例子。
-
There are encoding regions called exons and those are interrupted by non-coding regions called introns.
编码蛋白质的部分叫外显子,外显子被不编码蛋白质的内含子打断
-
That goes back to that idea of sort of discipline coding. It's easy to have assumptions about what you think are going to come into the program when you writ it. If you really know what they are use them as search, but if you think there's going to be some flexibility, you want to prevent the user getting trapped in a bad spot, and exceptions as a consequence are a good thing to use.
这又回到了规范编码的想法上来了,在你写代码的时候考虑,什么会进入你的代码的思考是简单的,如果你真的知道,他们是用他们来做搜索的,而你希望有一定的灵活性，你想要阻止用户,陷入一个艰难的境地,那么异常是非常实用的。

so I can tell you how Julius Caesar encoded his things.
我可以告诉你尤里乌斯·凯撒给文件编码的方式。
-
So you can figure out bugs and things like that
所以你能找出错误的编码之类的，
-
Some of the signals control a motor which spins metal-coded platters.
一些信号控制一个用于,金属编码磁盘的旋转。
-
When a gene gets expressed, that means its protein is produced.
一段基因得到表达,就意味着合成它所编码的蛋白
-
I'll talk about what that means, encoding insulin means in a minute, but there's a gene that tells your body what insulin looks like and that gets transcribed but only in those cells that make insulin.
一会儿,我将会讨论基因编码胰岛素的意义,所有细胞都含有相同的胰岛素基因,它决定胰岛素的结构以及如何被转录,但是只有胰腺细胞才能产生胰岛素
-
The DNA that encodes the proteins that are important to the life of that cell.
只发生于编码特定蛋白质的DNA序列,这些蛋白质对细胞而言至关重要
-
A pancreas--cell in the pancreas, for example, needs to make insulin and so the gene for insulin is transcribed.
举个例子,一个胰腺细胞,要分泌胰岛素,那么编码胰岛素蛋白的基因就会被转录
-
So I wrote a little program called "chart" that, based on some data I happened to hardcode into the program, shows us their numbers for the past several years.
我写了一个叫做“图表“的小程序，基于我在程序中硬编码的一些数据，向我们显示在过去几年中我们课程的人数。
-
We don't expect everybody to be a course six major, contrary to popular opinion, so for those are you not in that category, the second thing we want to do is we want to help students who don't plan to major in course six to feel justifiably confident in their ability to write and read small pieces of code.
和大众意见正相反，我们不希望所有人都变成course，six的主修学生，所以对于那些不在第一梯队里的人来说，我们想做的第二件事情就是,希望帮助还不想,主修这门课的人,都能获得在自己能力范围内,读写小编码的自信。
-
Now of the two complimentary sequences, one of them encodes the gene.
这两段互补序列,其中一段是编码基因的
-
A gene, let's say it's the gene for insulin.
这段基因,就假设是,编码胰岛素的基因吧
-
A section of DNA that is responsible for encoding a gene, let's say it's the insulin gene for example, might be some stretch of DNA on a certain chromosome inside your cells, inside the cells of the pancreas.
一段编码蛋白的DNA序列,我们就拿编码胰岛素的基因来举个例子,它也许是一段DNA基因序列,位于你胰腺细胞里的,某条染色体上
-
It operates in a similar fashion to DNA polymerase in that it denatures locally or opens up the double stranded DNA, but it's different in that it creates a new polymer from the DNA template in the language of RNA, using RNA nucleotides and not DNA nucleotides.
它的作用机制类似于DNA聚合酶,在局部使DNA双链变性,解旋,但不同的是,它合成了一个基于DNA模板的,使用RNA编码语言的新聚合物,即使用核糖核苷而非脱氧核糖核苷
-
Now the challenge is not just to get the DNA that encodes a gene into a cell, the challenge is to get it into the cell in a form where the cell can use it, can express it and make proteins from it.
现在的问题不仅在于,要将编码基因的DNA转进细胞,还要让它进入细胞之后,能够为细胞所用,能够表达并合成蛋白质
