遗传工程是70年代分子生物学中发展迅速的新领域,是一种崭新的科学技术。它给人们提供了按人类的需要和意愿来加工、转移遗传物质,以控制生物遗传特性和创造新品种的可能性。它为细胞分化、生长发育和肿瘤发生等基础研究提供了有效的实验手段。为工业、农业和医药卫生等领域研究的重大变革开拓了广阔的发展前景.广义的遗传工程包括细胞工程、染色体工程和基因工程.在医学上讨论遗传病治疗中所提到的遗传工程,主要是指基因工程或叫基因治疗。即按照需要,有选择地从某一生物细胞分离出某一基因(DNA 片段)或人工合成某一基因,通过运载体把它转移到
Genetic engineering is a rapidly developing new field in molecular biology in the 1970s and a brand new science and technology. It provides people with the human needs and intentions to process, transfer genetic material, in order to control biological genetic characteristics and the possibility of creating new varieties. It provides an effective experimental means for basic research such as cell differentiation, growth and development and tumorigenesis. Which has opened up broad prospects for the great changes in the fields of industrial, agricultural and medical and health research.General genetic engineering includes cell engineering, chromosomal engineering and genetic engineering.In the medical discussion of genetic diseases mentioned in the genetic engineering, the main Refers to genetic engineering or gene therapy. That is, a gene (DNA fragment) is selectively isolated from a certain biological cell or a gene is artificially synthesized as necessary, and transferred to a
