下面为大家整理一篇优秀的essay代写范文 -- “Pandora's Box”，文章讲述当我看到基因疗法有潜在的风险时，我有点害怕。无法轻易将基因直接插入细胞。相反，它通常必须使用称为向量的载体来传递。最常见的基因治疗载体是病毒，因为它们可以识别某些细胞并将遗传物质携带到细胞的基因中。视频中的科学家承认DNA的变化可能是随机的，这意味着不确定性和风险。他们的观点和理论证明了这一点。基因科学发展和应用的危险性。
This video is thought-provoking and is a serious warning to people.We can not just pay attention to the benefits of genetic development.Nobody is able to deny that the side effect of genetic engineering should be attached importance.
When I saw that gene therapy has some potential risks,I was a little scared. A gene can't easily be inserted directly into your cells. Rather, it usually has to be delivered using a carrier, called a vector. The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells' genes.Secientists in the video admit that the changes of DNA may be random,which means the uncertaintity and risks.Their opinion and theory proves the dangerousness of genetic science's development and application.
What'more,prejutice problem is another challenge.According to the authoritic survey,prejudice is, as the name implies, the process of "pre-judging" something. It implies coming to a judgment on a subject before learning where the preponderance of evidence actually lies, or forming a judgment without direct experience. Holding a politically unpopular view is not in itself prejudice, and politically popular views are not necessarily free of prejudice. When applied to social groups, prejudice generally refers to existing biases toward the members of such groups, often based on social stereotypes; and at its most extreme, results in groups being denied benefits and rights unjustly or, conversely, unfairly showing unwarranted favor towards others.This can be seen even when the resource is insignificant. In the Robber’s Cave experiment, negative prejudice and hostility was created between two summer camps after sports competitions for small prizes. The hostility was lessened after the two competing camps were forced to cooperate on tasks to achieve a common goal.Scientists major in DNA must be faced with prejudice sometimes and suffer some stress when they work.
I consider DNA project more deeply after watching this video.Thanks for this experience.=
