有关基因的英文文章

“种瓜得瓜，种豆得豆”，这个众所周知的生命现象却包含了神秘莫测的根源。古往今来，人类从未停止过对这根源的探求。基因的发现终于揭开了人类乃至自然界一切生命的奥秘。

Look in the mirror and admire an original masterpiece — a one-off, never to be repeated work of art.You are unique and that is partly due to your combination of genes.Unless you are an identical twin it's a combination which has never been seen before.

Seeing Your Genes

Have another look in the mirror.Now compare what you see with two photographs.One of your mother and one of your father.You can see the telltale signs of your genes in all three of your faces.Do you have the“Bailey chin”, the“Harrison nose”or the“Smith dimple”? They are the result of certain genes.Some features run so strongly in families they become the origin of some of our best-known surnames.An obvious example is height, which was the inspiration for the surnames Long and Short.

How Do Genes Make Us Look Similar?

Genes do something very simple.They are the recipe for building another molecule called a protein.Almost everything in your body is either made of a protein or has been put together with the help of one.They are the crucial building blocks which underlay the formation of just about everything from the color of your skin to the precise layout of neurons in your brain.Your genes are a gift from your parents.A hand-me-down list of recipes for making endless proteins which together shape your body.If you can spot similarities in the faces of your family then you are seeing the end products of your shared genes.

Why Should We Be Different?

Genes are made from a molecule called DNA.Along its length, a string of chemicals are arranged in an important pattern.That pattern is actually a code that carries protein-building instructions.If the pattern is altered a different protein will be produced.Different genes are the result of different patterns of DNA.

我是谁——基因为你解谜

请你照照镜子，欣赏一件自创的杰作吧——你是一件不可复制的艺术品，你是独一无二的!这在一定程度上是你的基因组合使然。除非你是双胞胎中的一个，否则你的基因组合就是前所未有的。

认识自己的基因

你再照照镜子，将镜子中的你和两张照片一起对照着看，一张是你母亲的，一张是你父亲的。你会清楚地看到三张脸上有相似基因的迹象。你是否有一个“贝利”的下巴，“哈里森”的鼻子，“史密斯”的酒窝?所有这些，都是某些特定基因起作用的结果。有些家庭成员的外形特征非常明显，由此出现了一些众所皆知的姓氏。一个明显的例子就是：如“朗”(此处英文是long，意为“高个子”)和“肖特”(英文为short，意为“矮子”)等都是以身高特征为绰号从而演变成姓氏的灵感来源。

基因如何使我们相像?

基因的工作原理很简单：它是制造另一种分子——蛋白质的配方。你身体的每个部位几乎都由蛋白质构成，或在蛋白质的帮助下组成。它们犹如砌房的基石一样至关重要，是形成人体构造的基础——从肤色乃至精细的大脑神经元分布等。你的基因乃你父母所赐。一张基因遗传单上写满了配方，它能制造出不计其数的蛋白质，这些蛋白质组合起来又构成你的身体。如果你能看出家人脸上的相似之处，你所见到的就是你们共同基因的终端产物。

我们为何会不同?

基因是由叫作DNA的分子组成，DNA则由一长串的化学分子按重要的序列排列而成。这个序列实际上就是一个携带构建蛋白质指令的密码。序列一旦改变了，合成的蛋白质就会不同，而不同的DNA序列产生的基因也不同。
