That's why molecular biology, one of the reasons why it's turned out to be such a powerful tool, because if you can think creatively you can find all different ways to using these very simple principles to recombine molecules, to make unique new DNA sequences.

这就是分子生物学,如此有用的原因之一,因为如果你有创造力,你可以用各种方法,运用这些简单的原理来重组分子,创造独特的DNA新序列

The best way to label this DNA is by designing probes or labels that hybridize with specific sequences that you're interested in.

最好的标记方法是,设计出能与你感兴趣的,特定基因序列杂交的,分子探针或标签

The DNA molecule here has been spread apart, opening up two single stranded DNA's which have complementary base sequences because they were double stranded DNA.

这里DNA分子被分开,形成两条单链DNA,这两条单链碱基序列互补,因为它们是由双链DNA解旋形成的

Most restriction enzyme also recognize symmetric sequences of DNA, GAATTC for example.

大多数限制性内切酶,也能识别DNA的对称序列,例如GAATTC

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

Certain segments of DNA are being converted into RNA, and whereas in replication, you have to copy the whole genome, the whole - all of the chromosomes, all of the DNA contained in the chromosomes of the cell in order to completely replicate it; transcription only works on particular sequences of DNA.

特定的DNA序列被转录为RNA,在复制的过程中,整条染色体都被复制,包括其中的全部DNA序列,都被分毫不差地复制下来,以保证复制的完整性,而转录过程只发生在特定的DNA序列上
