1973年,在美国的一次分子生物学学术会议上,出现了基因(DNA)可以人工重新组合并在细菌中繁殖的苗头。后来DNA重组技术迅速发展,一个新兴领域——遗传工程(基因工程)应运而生,并与细胞融合技术、酶的固定化技术等一起,形成了现代生物技术。在以后的短短几年内,基因工程就和传统的生物工艺学,特别是发酵工艺学结合,在许多人们生活密切相关的领域(如医药、食品、农
In 1973, at a conference of molecular biology in the United States, signs emerged that genes could be artificially recombined and multiplied in bacteria. Later, the rapid development of DNA recombination technology, an emerging field - genetic engineering (genetic engineering) came into being, and cell fusion technology, enzyme immobilization technology together to form a modern biotechnology. In just a few short years, genetic engineering has been combined with traditional biotechnology, especially fermentation technology, in many areas where people's lives are closely linked (such as medicine, food, agriculture
