It's a long sequence of instructions, it starts at the beginning, walks through, may jump around a little bit, but eventually comes down at the end. It's okay for the things you're doing for the early problem sets.
这是一长串指令,从开端开始,向前步行,偶尔来回跳一会儿,但是最终会走到结尾,这些足以解决最初级的问题。
Well at some level it is an ordered sequence of characters. Right? Now it is not represented this same way. You don't see strings inside these open parens and closed parens.
现在字符串不是用这种方式表达的,你没有看到字符串里有开括号闭括号,字符串中间也没有逗号,但是它有同样的属性。
one is to look at the sequence of event, look at these sequence in October 29, stock market crashed, two month later, 9% unemployment peaked at 9%.
一种是看看事件发生的时间,看看顺序,10月29号,股票市场崩溃,两个月后,失业率上升到。
Well, that specialized region - now in this diagram here, this is the axon of one cell, the first cell in a sequence and that axon meets the dendrite of another cell at a special region called a synapse.
图中这里的这一特定区域,是一个细胞的轴突,是这一列中的第一个细胞,而轴突,和另一个细胞的树突,在一个叫做突触的地方相遇
I'm going to delete that arrow and actually draw s2 as pointing to this chunk of memory because whereas before this sequence of chars might have lived at address 71 or whatever, well, this one might live at 91.
我不会把那个箭头删除,实际上我画了s2作为,这块内存的指针,因为,这个字符序列存储在地址71或其它的地方,这个可能存储在91的地方。
So I'm going to go over here, and I'm going to type test search-- I can type and if you look at your handout, it's just a sequence of tests that I'm going to do OK. So initially, I'm going to set up the list to be the first million integers.
大家可以看看你们的课堂材料,那儿有一些我要做的实验,好,一开始我先去建立个,含有一百万个integer的数组,对,这有点儿简单,但是这给我提供了这样一个有序的数组。
If I took this same restriction enzyme and tried to cut the chromosomal DNA of a sickle patient, it wouldn't cut at that point because the wrong sequence is there.
而如果我用同样的限制酶,去切割病人的染色体DNA,那该酶是不会起作用的,因为基因序列不对
There are hundreds,thousands of them known now, and each one has a specific character and one aspects of its character is that it only binds and cuts at a particular sequence of DNA.
已知的有成百上千种,每一种都有自己的特性,特性之一是,只结合和切割特定的某一种DNA序列
Every cell in your body has exactly the same DNA; that is if I could stretch out all the DNA and look at the base pair sequence, the sequences of bases along all the DNA in your chromosomes, they'd be identical in all the cells.
身体内每一个细胞都有完全相同的DNA,如果我把整条DNA展开,然后检查其碱基对的顺序,你体内每个细胞中染色体上,DNA的碱基对顺序,都是完全相同的
The goal of that was to take for a typical human, or for a typical - in the case of the human genome project maybe you're looking at fruit flies, you want to look at all the DNA in a fruit fly, but to look at the sequence of base pairs that makes up human DNA and write them all out; we'll talk about that later.
这个计划的目的是,建立一个有代表性人类的基因顺序,或者说是典型的人类基因组,就人类基因组计划来说,或许你在研究果蝇,你想观察果蝇内的所有DNA,而人类基因组计划是观察组成人类的,DNA的碱基对顺序并且将它们记录下来,我们不久之后会讨论这些内容
