生物工程又叫生物技术或生物工艺学.广义地说,生物工程就是为了人类的需要而将生物系统加以调节和控制的技术,因此,古老的农牧业和酿造业技术也可以包括在内.但是目前一般所谓的生物工程,是包括基因工程、细胞工程、酶工程和发酵工程在内的建立在现代生命科学基础之上的生物技术的总称.基因工程是把一种生物的DNA提取出来,加以切割,把带有所需性状基因的DNA片段转移到另一种生物的细胞中去,使后者获得前者的遗传信息,从而创造出新的生物类型.细胞工程包括动植物的细胞组织培养和原生质
Bioengineering is also called biotechnology or biotechnology.Widely speaking, bioengineering is a technology that regulates and controls biological systems for the needs of humankind. Therefore, ancient farming and animal husbandry and brewing technologies can also be included. However, the so-called bioengineering is a general term for biotechnology based on modern life sciences, including genetic engineering, cell engineering, enzyme engineering and fermentation engineering.Gene engineering is to extract the DNA of an organism, To be cut, the DNA fragment with the desired trait gene transfer to another biological cells, so that the latter access to the former genetic information, thus creating a new biological type.Cellular engineering including animal and plant tissue culture And the protoplasm
