高分英语作文1:Advantages and disadvantages of genetic engineering
The advantages and disadvantages of genetically modified food have more advantages: they can improve the yield per unit area of crops, reduce the production cost, through the transgenic technology can improve the resistance of crops to blast, antiviral ability, improve agricultural resistance, prolong the minimum storage capacity, and meet the needs of people's living standards can greatly shorten the development time of crops Get rid of the influence of off-season and climate, break the limit of low-cost supply in four seasons, continuously cultivate new varieties, and produce genetically modified food that is beneficial to human health.

转基因食品的优缺点转基因食品有更多的优点:它们可以提高作物的单位面积产量,降低生产成本,通过转基因技术可以提高作物的抗瘟性,抗病毒能力提高农业抗性,延长贮藏性最小,而满足人们生活水平不断提高的需求可以使农作物的发育时间大大缩短,可以摆脱淡季、气候的影响,打破四季低成本供应的界限,不断培育新品种,生产有益于人类健康的食品转基因食品及缺点:所谓的产量不受环境影响的情况下,如果遭遇雨雪自然灾害,也可能减产更严重。
万能作文模板2:基因工程的优缺点
The advantages and disadvantages of the Three Gorges Project on the Yangtze River are discussed. The advantages and disadvantages of the Three Gorges Project on the environment are greater than the disadvantages in controlling the ecological balance. The benefits of the Three Gorges Project are mainly in the middle, including reducing the damage of flood disaster to the ecological environment, reducing the coal pollution to the environment, and reducing the sedimentation of Dongting Lake.
The adverse effects are mainly concentrated in the reservoir area, except for farmland inundation, landscape changes and large scale In addition to migration, the rare species, tailwater, landslides, earthquakes, etc. in shangdui town have certain impacts on terrestrial animals and plants.

满分英语范文3:基因工程的利与弊
Genetic engineering is a set of techniques used to change the genetic structure of cells, including the transfer of genes within species and across species boundaries to produce improved or new organisms. New DNA can be first isolated and copied from the genetic material of interest, using molecular cloning method to generate DNA sequence, or by synthesizing DNA, and then inserting this structure into the host organism, the gene can be removed or "knocked out". Using nuclease gene targeting is a different technology, which uses homologous recombination to change endogenous genes and can be used for deletion Gene, exon deletion, gene addition, or point mutation gene engineering technology has been applied in many fields, including research, agriculture, industrial biotechnology and pharmaceutical enzymes used in laundry powder.
Now transgenic cells, experimental transgenic cell lines and transgenic animals (such as mice) are used to produce drugs such as insulin and human growth hormone. Zebrafish has been used for research purposes Genetic crops have been commercialized.

基因工程是一套用来改变细胞遗传结构的技术,包括在物种内部和跨物种边界转移基因,以产生改良的或新的有机体。新的DNA可以通过首先分离和复制感兴趣的遗传物质,用分子克隆方法产生DNA序列,或者通过合成DNA,然后将这个结构体插入宿主有机体中,基因可以被移除,或者被“敲除”,使用核酸酶基因靶向是一种不同的技术,它利用同源重组来改变内源基因,并可用于删除基因、删除外显子、添加基因,或者引入点突变基因工程技术已经应用于许多领域,包括研究、农业、工业生物技术和用于洗衣粉的药物酶,现在转基因细胞、实验性转基因细胞系和转基因动物(如小鼠)生产胰岛素和人生长激素等药物斑马鱼被用于研究目的,转基因作物已经商业化。
