每次分裂后,端粒变短一段时间后可能发生的一件事是染色体上的基因片段会断裂。
So after each division, the telomeres get shorter and one of the things that may happen after a while is that pieces of the genes themselves get broken off the Chromosomes.
基因改造,就是借助某种特别的酶,删除选中基因片段。
Genetic modification can be used to cut out selected pieces of DNA (or genes) using special enzymes.
首先,一些多余的基因片段被永久性地写入细胞染色体组。
First, they permanently inserted the extra genes into the reprogrammed cell's genome.
So you made somehow an anti-sense polynucleotide to the insulin gene or some fraction of the insulin gene.
这样你就合成了,胰岛素基因的反义多聚核苷酸链,或者说胰岛素基因的片段
How we do that will be clear in a few minutes, but this polylinker as is described down here is a site where you can clone in genes.
马上你们就清楚这该怎么做了,这里所说的多克隆位点,就是你能把基因片段插进来的位点
It's only going to bind to fragments that contain that piece of the gene, and it will make those visible to you in some way so you can see where your gene traveled.
它只会和有那段序列的片段结合,从而能让你看到那段片段在哪里,你就可以知道目标基因片段到了哪个位置
