高分英语作文1：Gene mutation

Genetically modified food is a product brought to us by science. With less and less cultivated land, genetically modified food will play an increasingly important role. If the problem of food shortage in the world can be solved by using genetically modified technology, genetically modified food is not very good in today's world. 基因突变的英语作文_小学高分英语作文5篇

It is a new thing, a new thing, and people need time to promote its acceptance, We can't put new things in the cradle and insist on it at the beginning. We can't eat genetically modified food. You think the hybrid rice we don't eat is a kind of genetically modified food, but we can open it.

If they can transfer genes from other crops to other crops through soybean transgenic technology and use atmospheric nitrogen in their fertilizer to transfer genes to humans, this is the two sides of everything, In particular, science and technology is a double-edged sword. Genetically modified food has its disadvantages, just as some people worry, because it will not change, it will destroy genetic evolution, and the nutrition in genetically modified food is not like that. People's propaganda worry is understandable.

It takes time to accept a new thing, but we should also see their advantages, I think as time goes by As time goes by, genetically modified foods will be accepted.

转基因食品是科学带给我们的产物，现在耕地面积越来越少，转基因食品将发挥越来越重要的作用，如果利用转基因技术能够解决世界粮食短缺问题，那么转基因食品在当今世界还不是很好，是一种新生事物、新事物、人需要时间来促进它的接受也需要一段时间，我们不能把新的东西放在摇篮里，一开始就坚持它，不能吃的转基因食品你认为我们不吃的杂交水稻是一种转基因食品，但我们可以打开它，如果他们能通过大豆转基因技术，利用大气氮在他生产的肥料中向其他作物基因转移在人类身上，这是一切事物的两面性，尤其是科技，科技是一把双刃剑，转基因食品有它的缺点，就像有些人担心的那样，因为它不会改变，会破坏遗传进化，等转基因食品里面的营养又不是那样的，人们的宣传担心是可以理解的，接受一个新事物需要时间但是我们也应该看到它们的好处，我想随着时间的慢慢过去，转基因食品会被人们接受的。

A study by Johns Hopkins University on Tuesday showed that an individual's genome changes during a person's lifetime due to environmental or nutritional factors, which may explain why diseases such as cancer change with age, researchers have found that so-called epigenetic markers occur in a person's DNA sequence over a lifetime The extent to which this change has changed is similar among family members. "We're starting to see epigenetics as the center of modern medicine, because epigenetic changes, unlike DNA sequences, are the same in every cell, and it could be the result of diet and other environmental exposure," said Andrew Feinberg, Professor of molecular biology and genetics at the University. "Epigenetics is likely to occur in diseases such as diabetes, autism and cancer In a study published in the Journal of the American Medical Association, he added that the team analyzed the DNA sequences of people who participated in the Reykjavik age group study.

Participants in the Reykjavik heart study, formerly known as the Icelandic Reykjavik heart study, provided DNA samples between and then scientists measured changes in methylation levels, the main epigenetic modification In about one-third of the samples, methylation levels changed after a few years. "Inappropriate methylation," said vilmundur, Professor of cardiovascular genetics at the University of Iceland "Too high a level may turn off the necessary genes, too few may turn on the genes at the wrong time or in the wrong cell," said gudnason, adding that "what we see is detectable changes over time," added Daniel farIn, associate professor of epidemiology at Johns Hopkins University's School of public health at the school of public health It does change with age, "and this change may also be genetic, which may explain why some families are more susceptible to certain diseases than others.

约翰霍普金斯大学周二的一项研究表明，在一个人的一生中，个体的基因组会受到环境或营养因素的影响而发生变化，这也许可以解释为什么癌症等疾病会随着年龄的增长而发生变化，研究人员发现，在一个人的DNA序列上，所谓的表观遗传标记会在人的一生中发生改变这种变化的程度在家庭成员中是相似的。“我们开始看到表观遗传学是现代医学的中心，因为表观遗传学的变化，不同于DNA序列在每个细胞中都是一样的，它可能是饮食和其他环境暴露的结果，”安德鲁·范伯格说，该大学分子生物学和遗传学教授“表观遗传学很可能在糖尿病、自闭症和癌症等疾病中发挥重要作用，”他在《美国医学会杂志》上发表的研究中补充道，研究小组分析了参加雷克雅未克年龄段研究的人的DNA序列，以前被称为冰岛雷克雅未克心脏研究的参与者在年和年之间提供了DNA样本，然后科学家们测量了甲基化水平的变化，这是主要的表观遗传修饰，在大约三分之一的样本中，甲基化水平在数年后发生了变化“不适当的甲基化”冰岛大学心血管遗传学教授维尔蒙杜尔古德纳森（Vilmundur Gudnason）说：“水平过高可能会关闭必要的基因，太少可能会在错误的时间或错误的细胞中开启基因，”我们看到的是随着时间的推移可检测到的变化，约翰霍普金斯大学彭博公共卫生学院流行病学副教授丹尼尔法林补充说：“这向我们证明了个人的表观遗传学确实会随着年龄的增长而变化，”这种变化也可能是遗传性的，这也许可以解释为什么有些家庭比其他家庭更容易受到某些疾病的影响。

Because the transgenic animal system breaks the interspecific isolation produced in nature and makes the organism flow with very far relationship between plants, it will have a global impact on the whole life science. Transgenic animal technology was recognized as the fourth generation technology of genetic transmission chain analysis, somatic cell genetics and gene cloning at the first International Conference on gene mapping The tenth turning point in the history of Biology.
