高分英语作文1：Do experiments with DNA

DNA exists in all cellular organisms and viruses, it contains the genetic information of the organism. DNA is the abbreviation of deoxyribonucleic acid, which is composed of two anti parallel chains (double helix), composed of sugar, a phospholipid unit and different bases. The two chains are connected by hydrogen bonds between base pairs.

Although the main chain of phosphate sugar is outside, the main chain of phosphoric acid remains unchanged in one chain, while the bases of adenine, thymine, guanine and cytosine may be different, but the sequence of bases in the double chain determines the inheritance code, which means that the sequence and distribution of bases determine all heritability of an organism This is a very accurate code, even if a letter in the DNA code is wrong, it can lead to disastrous consequences. A unit (nucleotide sequence) responsible for the double helix of a trait is called a gene.

中文翻译：

DNA存在于所有的细胞有机体和病毒中，它包含有机体的遗传信息，DNA是脱氧核糖核酸的缩写，由两条反平行链（双螺旋）组成，由糖、一个磷脂单元和不同的碱基组成。两条链通过碱基对之间的氢键连接在一起，虽然磷酸糖的主链在外面，但磷酸的主链在一条链内保持不变，而腺嘌呤、胸腺嘧啶、鸟嘌呤和胞嘧啶的碱基可能不同，但双链中碱基的顺序决定了遗传密码，这意味着碱基的顺序和分布决定了一个有机体的所有可遗传性状，这是一个非常精确的密码，即使是DNA密码中的一个字母出现错误，也会导致灾难性后果。负责某一性状的双螺旋链的一个单位（核苷酸序列）被称为基因。

First, animals and human beings have equal lives. Human beings have no right to deprive an animal of what to eat except for the second life. People do experiments (with more fur) just like slaughtering a batch of animals.

He was once an experimental student in medical college. The word "mouse light" refers to more than ten million lives of any student (excluding other experimental animals). Therefore, experimental animals all over the world The second sacrifice is the closed group animals that are deliberately cultivated by human beings.

Even if the simple animal blood relationship intermarriage is simple, more animal varieties produce human congenital defects, such as the lack of T cells in nude mice, while the spontaneous hypertensive rats, spontaneous epilepsy animals, etc., are also inhumane. It can be said that it is a kind of behavior that violates the natural law, and is more important, from small experimental animals to limited animals In a small space, it is the most basic way for animals to survive, and the choice of power makes them hate doing experiments. Many experiments are deliberately copying the diseases of animal models.

In other words, human groups, treats or does not treat the sick animals, and finally implements them.
