Scientists have used gene splicing to develop modified crop plants, new drugs, pest-resistant plants, and animals that grow rapidly (Figure 4-9). They have also created genetically engineered bacteria to extract minerals such as copper from their underground ores and to clean up spills of oil and other toxic pollutants. 

Bioengineers have developed many beneficial GMOs: chickens that low –cholesterol eggs, wheat that thrives in drought condition, bananas that don’t rot on the way to market, and tomatoes with genes that can help prevent some types of cancer. 

Genetic engineers have also produced two mice, the Schwarzenegger mouse, which has muscle-building genes, and the marathon mouse, which never seems to tire. And they are in hot pursuit of a Methuselah mouse that can live much longer than a conventional mouse.


科學家們利用基因剪接開發改良作物,新的藥物,抗蟲植物和迅速增長的動物(圖4-9 ) 。他們還建立轉植基因細菌中提取礦物質(有用的物質),像取出礦石中的銅和清理洩漏的石油和有毒污染物。

生物工程已經開發了許多有益的轉植基因生物:雞會生低膽固醇雞蛋,小麥生長在乾旱條件下,比較不會爛掉的香蕉推向市場。西紅柿的基因,可以幫助防止某些類型的癌症。

遺傳工程師們還製作了兩個老鼠,例如:施瓦辛格鼠,這增強肌肉的基因老鼠,以及馬拉松鼠,這種老鼠似乎永遠不會疲勞。他們在緊迫的追求瑪士撒拉鼠,這種老鼠可以比傳統老鼠活更久。
