生物技术,也称生物工程,包括遗传工程、细胞工程、酶工程、发酵工程等等。生物技术的主要任务是:(1)利用微生物、植物细胞、动物细胞或细胞的一部分(例如酶)大量生产在医学、农业等方面有重要用途的物质;(2)不用传统的遗传育种技术,而是用重组DNA技术、细胞融合和其他方法,创造新的微生物、细胞、植物或动物;(3)应用分子生物学深入揭示基因的结构与活动,以便能按人类的需要去改变 Biotechnology, also known as bioengineering, including genetic engineering, cell engineering, enzyme engineering, fermentation engineering and so on. The main tasks of biotechnology are: (1) to mass-produce substances of important use in medicine, agriculture, etc., using microorganisms, plant cells, animal cells or a part of cells such as enzymes; (2) without traditional genetic breeding techniques, But to create new microorganisms, cells, plants or animals using recombinant DNA technology, cell fusion and other methods; (3) to use molecular biology to reveal the structure and activity of genes in depth so that they can be changed according to human needs
