高分英语作文1：Advantages and disadvantages of DNA

With the development of information technology, there are more and more opportunities for people to choose their favorite products. However, the more commodities they have, the more confused they feel when they choose the products they like. Advertising stands out and bears the responsibility of choosing the products they like.

However, advertising has its advantages and disadvantages. Some people agree with it, while others are on the contrary. On the one hand, I am in a neutral position.

Advertising helps people better Product advertisements always tell people the advantages and functions of products. People can buy what they want by reading advertisements. Advertisements are free to consumers.

Advertisements are much more interesting than the instructions on the boxes, because advertisements contain various factors, such as pictures, videos, sound plots, etc. You don't think it's a good way to choose a product. On the other hand, in order to attract the target customers, advertisements are sometimes alluring and deceptive.

Advertisers will fill in the contents of the decoration. No matter what dirty measures they take or the serious damage they may bring to the advertisements, they always exaggerate the advantages and functions of the products and mislead consumers to buy things that are not worth summarizing, Advertising is good for one side and the other side. If we only use them as reference, it is good, but if we rely on them to buy things, we may eventually suffer losses.

随着信息化的发展，人们选择自己喜欢的商品的机会越来越多，但商品越多，人们在选择商品时就越感到困惑，广告脱颖而出，承担着人们选择自己喜欢的产品的责任，但广告也有利弊，有些人赞成，有些人则相反，我一方面处于中立地位，广告帮助人们更好地了解产品广告总是告诉人们产品的优点和功能人们可以通过阅读广告买到他们想要的东西，广告对消费者是免费的，广告比包装盒上的说明有趣得多，因为广告包含各种因素，如图片、视频、声音情节等等。你不认为这是一种选择产品的好方法另一方面，为了吸引目标客户，广告有时具有诱惑力和欺骗性，广告主会把装潢表达的内容填满，不管他们采取了什么肮脏的措施或可能给广告带来的严重损害，总是夸大产品的优点和功能，误导消费者购买不值得总结的东西，广告有好处一方和另一方，如果我们只把它们作为参考，那是好的，但如果我们依靠它们来买东西，我们最终可能会遭受损失。

As for the text I learned, I thought a lot after learning about cloning technology. Therefore, I wrote down the idea diary in my mind: DNA if my mother has a smiling mouth, then I will have the same children. If my father has a pair of big eyes, if my mother is very short, I will have one too.

I may also be short, my parents have them Black hair, so my hair will also be black. I really want to clone myself. I don't have to go to school instead of that.

I can play all the time. Cloning "I" will replace medna to study.

满分英语范文3：dna的利与弊

What is deoxyribonucleic acid, or deoxyribonucleic acid, is the genetic material of human beings and almost all other organisms. Almost every cell in the human body has the same DNA. Most of the DNA is located in the nucleus (called nuclear DNA there, but a small amount of DNA can also be found in mitochondria) (where it is called mitochondrial DNA or mtDNA DNA DNA) The information in DNA is stored in encoded form and consists of four chemical bases: adenine (a guanine (g-cytosine (C and thymine)) (t-human DNA consists of about a billion bases, and these bases are the same in all people the order or sequence of these bases determines the information needed to build and maintain an organism, similar to the letters in the alphabet In a certain order to form words and sentences, DNA bases pair with each other, a and T, C and G, forming units called base pairs.

Each base is also linked to sugar and phosphate molecules. Base, sugar and phosphate are called nucleotides. Nucleotides are arranged in two long chains to form a spiral structure called double helix.

The double helix structure is a bit like a ladder. Base pairs form a ladder like rung. Sugar and phosphate molecules form a vertical side block of ladderan.

The important feature of DNA is that it can be copied, Or copy each strand of DNA in its own double helix, which is crucial for cell division, because each new cell needs an exact copy of the DNA from the old cell. DNA is a double helix, formed by base pairs attached to the sugar phosphate backbone.
