转基因是什么?对公众来说,鱼的基因可以转给番茄,使番茄更易于保存;微生物的基因可以转到棉花上,使棉花具备抗虫的能力,这是很难理解的。而早在20世纪80年代中期,我国的科学家就开始介入这种高难度的组合游戏了。比如番茄由于富含水分很不耐冻,科学家将生活在低温环境下的一种深海鱼的基因,移植到番茄细胞内,就培育成了耐冻的转基因番茄。 What is GMO? To the general public, fish genes can be transferred to tomatoes to make it easier for tomatoes to be preserved. It is hard to understand that the genes of microorganisms can be transferred to cotton to make cotton resistant to insects. As early as the mid-1980s, our country’s scientists began to intervene in this highly complex combination of games. For example, tomatoes are very cold-resistant due to high water content. Scientists transplant the genes of a deep-sea fish living in a low-temperature environment into tomato cells to cultivate a freeze-thaw-resistant transgenic tomato.
