Bacteria have defences against viruses in the form of chemicals called restriction enzymes, which chop up foreign DNA.
细菌有一种对病毒的防御机制:一种叫做限制性内切酶的化学物质可以切断外源dna。
As a cell replicates, the foreign DNA is absorbed and the genes in question are modified by the non-matching short sequences.
当细胞复制时,外来基因被吸收,相关基因被非配对短序列修饰。
Current methods use viruses or chemicals to bring foreign DNA inside cells, but these make permanent changes, which could have their own complications.
当前的方法使用病毒或者化学物质向细胞中引入外来dna,但是这些操作将带来永久性的改变,会引起其特有的并发症。
In this case, if everything goes right, you inject the DNA into the pronucleus, you implant this fertilized egg into a foster mother, the mother gives birth to offspring, it develops and when it develops this foreign DNA is in the offspring.
如此一来,如果一切顺利,DNA成功注射进原核,受精卵成功植入代孕母亲,成功的孕育了后代,后代健健康康的长大,目的基因就成功的整合进了后代的基因组
This concept of introducing foreign genes, genes that are made of recombinant DNA into animals using this kind of technique is widely used in biomedical research.
这种通过基因重组,来向动物体内导入外源基因的方法,广泛应用于,各种生物医药的研究中
