  • 《遗传法》

    Two scientists examining X-ray images related to the Human Genome Project in a lab.

    We're still working on it!
    ::我们还在努力呢!

    The Human Genome Project started in 1990 with the lofty goal of sequencing the complete set of human DNA. This project was completed in April 2003, ahead of schedule and under the budget set for it (a rare occurrence for a government project). With this knowledge, we can now identify genetic disorders quickly and personalize treatment for many diseases. However, much work still remains to fully understand the connections between specific DNA sequences and specific diseases.
    ::人类基因组项目始于1990年,其崇高目标是对全组人类DNA进行排序,该项目提前于2003年4月完成,在为该项目设定的预算下(政府项目很少发生)完成,有了这一知识,我们现在可以迅速识别遗传疾病,并对许多疾病进行个性化治疗,然而,仍需做大量工作才能充分理解具体DNA序列和特定疾病之间的联系。

    The Genetic Code
    ::《遗传法》

    Each particular organism contains many molecules that are specific to that organism. The particular sequence of DNA is responsible for the production of all of the different proteins that are present in each and every living thing that has ever inhabited the Earth. How does that work? Cells use the unique sequence of DNA bases to decide which proteins to synthesize. A gene is a segment of DNA that carries a code for making a specific polypeptide chain. The cell essentially decodes the DNA in order to make whatever and proteins are needed by that organism.
    ::每个生物体都含有许多与该生物体特有的分子。 DNA的特定序列是生产存在于地球上的每一种生物中的所有不同的蛋白质。 这如何运作? 细胞使用DNA基础的独特序列来决定要合成的蛋白质。 基因是DNA的分部分, 含有制作特定聚谱化物链的代码。 细胞基本上解码了DNA, 以便制造该生物体所需要的任何物质和蛋白质。

    The genetic code works as a series of three-letter codes. Each sequence of three letters, called a triplet, corresponds to one of the twenty common . The triplets are read by the cell, one after the other, in the process of . Table shows all of the possible triplets and the amino acids that result from each three-letter code.
    ::基因代码是一系列的三字母代码。 三个字母的顺序, 称为三字母, 对应20个常见字母中的1个。 3个字母的顺序由细胞阅读, 一个接一个, 由细胞阅读。 表格显示了每个3字母代码中的所有可能的三字母和氨基酸。

    The DNA code word GCA corresponds to the amino arginine, while the DNA code word TCG corresponds to the amino acid serine. Most amino acids are represented by more than one possible triplet code, but each triplet code yields only one particular amino acid. Three of the DNA code words (TAA, TAG, and TGA) are stop or termination code words. The translation of a DNA base sequence begins with a start code word and runs until a stop code word is reached. 
    ::DNA代号 GCA 与 氨基亚琴尼 对应,而 DNA 代号 TCG 则对应 氨基酸 尿液 。 大部分氨基酸 由 不止一个可能的三胞胎代号代表, 但每个三胞胎代号只产生一个特定的氨基酸 。 DNA 代号中的三个词( TAA、 TAG 和 TGA ) 是 停止或终止代号 。 DNA 基序的翻译从一个起始代号开始, 运行到一个停止代号达到为止 。

    Even with only four different bases, the number of possible nucleotide sequences in a DNA chain is virtually limitless. The particular DNA sequence of a particular organism constitutes the genetic blueprint for that organism.  This genetic blueprint is found in the nucleus of each cell of the organism and is passed on from parents to offspring. The incredible diversity of life on Earth stems from the differences in the genetic code of every living thing.
    ::即使在四个不同的基点上,DNA链中可能的核糖酸序列数量几乎是无限的。特定生物的DNA序列构成了该生物的基因蓝图。这一基因蓝图存在于生物的每个细胞的核心,并且从父母传给后代。地球上生命的不可想象的多样性来自每种生物的基因编码的差异。
