近來新聞中經(jīng)常提及轉基因食品。你可以從字面意思得知,轉基因食品就是用產(chǎn)生了基因變化的生物生產(chǎn)的食品。這種改變可能是引入一個從其他物種中提取的基因。
最近,關于轉基因食品的有爭議研究引起了公眾關注。轉基因的好處包括它能夠培育出抗病植物。另外,轉基因也可以增加天然物種中所缺失的維生素。
然而,轉基因食品的引進有可能是災難性的。從一個物種中提取基因并植入另一物種被認為是一個巨大的飛躍,這也許會帶來一些可怕的后果。現(xiàn)在還沒有定論。但是,所有的轉基因食物在推向市場前都要經(jīng)過嚴格的評估。
Genetically modified foods (GM foods) are often mentioned in the news lately. You can literally get the meaning of genetically modified foods, which refer to the foods produced from organisms with specific genetic changes. The modification may be adding a gene from a different species to create a transgenic plant.
Recent controversial studies on genetically modified foods have drawn attention of the public. The benefits of genetic modification include being able to breed disease-resistant plants. What’s more, it can also add those vitamins that some natural varieties may lack.
However, the introduction of genetically modified foods can be disastrous. Taking genes from one species and inserting them into another is supposed to be a giant leap forward, which may result in some terrible consequences. There hasn’t been any final conclusion yet. However, all GM foods should be strictly assessed before being allowed on the market.
