何谓转基因技术?它是指用人工分离和修饰过的外源基因导入生物体的基因组中,从而使生物体的遗传性状发生改变的技术。利用转基因技术生产的食品,自然就是转基因食品。在早期生产转基因食品时,曾发生过“帝王蝶风波”。玉米是美国最主要的农作物,它易受病虫害侵袭,每年为此喷洒 What is a transgene technology? It refers to a technology that uses an artificially isolated and modified exogenous gene to be introduced into an organism’s genome, thereby altering the genetic traits of the organism.

In the early production of genetically modified foods, there has been a “monarch butterfly storm.” Corn is the most important crop in the United States. It is susceptible to pests and diseases.
