Here is a thin membrane, it's a polymer scaffold, and on that polymer scaffold scientists have placed some skin cells and they've allowed it to grow.
这是一张薄膜,它是一个聚合物支架,在这个支架上,科学家放了一些皮肤细胞,并让它们生长
They bring into proximity an amino acid so that instead of forming a new polymer of a nucleic acid, a polymer of an amino acids is formed.
同时它所携带氨基酸相互邻接,从而形成了一个氨基酸聚合物,而非核酸聚合物
A polymer is just a large molecule that's made up of repeated units.
聚合物就是由,重复单位构成的大分子
A polymer of amino acids is a protein.
而氨基酸聚合物就是蛋白质
You can say a polymer of DNA, for example, is four bases long, that means it has four of these repeat units and they go in the sequence from 5' to 3' of .
打个比方,要描述一个由,四个核苷酸单位构成的寡聚DNA,就是说它由四个核苷酸单位构成,并且从5'端到3'端的顺序为
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
You load them into the top of a gel and a gel is - in this case it's synthetic polymer gel but it looks very much like Jell-O.
你把它安置在一段凝胶上,凝胶是--,这种合成凝胶聚合物看上去很像吉露果冻
We're familiar with polymers, plastics in our daily life; the chairs that you're sitting on are made of a kind of a plastic polymer that is basically an organic chemical that is cross-linked together.
我们应该很熟悉聚合物,比如日常生活中的塑料就是,你们坐的椅子,就是由一种塑料聚合物构成,它由基本的有机化学物质交联在一起
