生物技术(即生物工程学)是近十年来崛起的一门新兴学科.它是在生物学、化学和工程学等领域中,利用经过遗传操作的生物体或生物体的机能,按既定的目的,进行物质的生物转化并加以利用的技术体系.这个技术体系由基因工程、细胞工程、酶工程和发酵工程等新兴技术组成,其中基因工程是生物技术的带头学科. 生物工程的蓬勃发展,特别是在基因工程的基础上出现了蛋白质工程以后,解决农业上所长期面临的问题已不再是遥远的事情.首先是利用基因重组技术培育农作物新品种.过去用杂交的方法培育新品种,要受到远缘作物细胞的相互排斥作用的限制,
Biotechnology (ie, bioengineering) is a rising discipline in the past decade. It is the use of genetically manipulated organisms or organisms in biological, chemical, and engineering fields, according to established goals. A technology system for the bio-transformation and utilization of substances. This technology system consists of emerging technologies such as genetic engineering, cell engineering, enzyme engineering, and fermentation engineering. Genetic engineering is a leading discipline in biotechnology. The vigorous development of bio-engineering, especially After the emergence of protein engineering on the basis of genetic engineering, solving the long-term problems faced by agriculture is no longer a distant matter. The first is to use genetic recombination technology to cultivate new varieties of crops. In the past, we used hybrid methods to cultivate new varieties. Affected by the mutual exclusion of distant crop cells,
