sure there are differences. We see that our manuscripts are not exactly like those fragments, but there is a remarkable degree, a high degree of correspondence so that we really can speak of a relatively stable textual tradition but still some fluidity.
当然其中会有差异，我们手中的这些原稿,一定和那些片段有细微差异，但在很大的程度上,我们能说是和那文本传统大致相符的,但还是存在一些差异。

If I cut up just DNA from the chromosome, what's called genomic DNA, then I'm going to have both exons and introns within the fragments that I create.

If you start with only one, you have two pieces of DNA, then you'll get 2 to the Nth fragments after N cycles because each cycle you're doubling the number.

The first step is to take the DNA fragments that we're interested in and put them into this vector by basically cutting open the double stranded DNA and inserting the gene that we like in the region where we've cut.

Now if I put them in contact with one another, the plasmid that's been opened and fragments of the DNA - special fragments that I've produced with the same restriction enzyme, they'll have the same sticky ends, they will naturally hybridize with one another.
