This is - what this diagram shows you is-- the forces that hold these individual strands of DNA into a double stranded form.

你们可以看看这个图表,演示了连接两条DNA长链为双螺旋,结构的化学力

You know this, you can - it's hard to pick up a newspaper or a news magazine without hearing some new application of DNA technology.

你知道的,你-,随便翻一份报纸或杂志,上面很少没提到DNA技术的某个新应用

It's totally synthetic, there's no micro-organism involved in making the DNA for you, You can do it very rapidly in a laboratory, and fairly inexpensively now.

完全是复制的过程,没有任何微生物参与制造DNA,你可以在实验室里迅速地进行,费用现在也相当便宜了

The cell is a fertilized egg, so you take a fertilized egg and you directly inject plasma DNA into the pronucleus, into one of the pronucleus--pronuclei.

供试细胞是受精卵,当你获得一枚受精卵,可以直接将胞质DNA注射到,它的一个原核中

Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.

核酸分子杂交表示,DNA在变性状态下可以恢复活性,和与其配对的单链形成稳定的双螺旋结构,只有在完全配对时才会发生这种情况

DNA is a double helix, you know this, the double helix was--the structure of DNA was discovered about the time that I was born you've always lived with it.

NA是双螺旋结构,众所周知,DNA的这种双螺旋结构,是在我出生的那个年代才被发现的,它就是你生命的一部分

Then we'll talk about engineering of DNA and why this has been such - not only a rapidly growing and advancing area but one that's so important for Biomedical Engineering.

然后我们会谈论DNA工程,以及为何它不仅,是一个向前飞速发展的领域,而且对生物医学工程十分的重要

In a normal cell DNA that DNA in the normal cell - this DNA gets cut by the restriction enzyme, so the sickle gene ends up - so that hemoglobin gene ends up in two pieces.

一个正常细胞的DNA,正常细胞里的DNA,会被限制酶所剪切,因此镰状血红蛋白基因--,不对,是正常血红蛋白基因被切成两段
