A quick glance（扫视） around any public gathering（汇集） will attest（证明） to the physical（身体的、物理的） diversity(多样性、差异) of the human population. 快速的向任何公众地方扫一眼将证明人类身体的多样性。 As scientists begin to map and analyze（映射和分析） the molecular details（分子细节 ）of the complete set（整套） of human genes,whose will it be? 科学家已经开始映射和分析人类基因整套的分子细节,会是谁的呢？ In many ways,describing the anatomy解剖 of the human genome基因组 will be similar to studying the human heart,for example,or the human brain. 在许多方面,描述了人类基因组的结构类似于研究人类的心,例如,或人类的大脑。 While there are small differences from person to person in the size and shape of these organs,most of the key characteristics are the same. 虽然人和人的器官在上大小或形状上有所差异，但主要特征是相同的。 Although human beings are distinct from one another,they are really very similar in most biologically important respects.That’s what makes us human. 尽管人性各不相同,但他们在生物学上大多数重要的方面真的非常相似。这就是我们人类。 So the map of the human genome can really be based on（立足于） information collected from many different people. And most of the information in that map will pertain（适合） to everyone. 所以人类基因组构图真的可以立足于许多不同人的信息。 那个构图上的大部分信息适合每一个人。 The tiny differences between any two people rest in only 2 to 10 million (out of the 3 billion total) nucleotide bases, an amount that computes to about 1 percent or less of their total DNA. rest in在于；依赖于 an amount总计，合计；相当于 computes计算 介于任何两个人之间细微的不同仅仅在于200万到1000万的含氮碱基，这个数量估计占他们全部DNA的1%或者更少。 Because these small differences vary from person to person, it doesnt matter whose genome it is. 因为这些小差异因人而异,所以是谁的基因组没有影响。 For some studies, the differences will be the focus of interest. In other cases, it will be the similarities. 对于一些研究,不同的是兴趣的中心。在其他情况下,这将是相似的。 Researchers（研究人员 ） at Baylor College of Medicine were given the assignment of mapping the sex chromosome（染色体 ） X and chromosome 17. 贝勒医学院的研究人员被给予映射X染色体和17号染色体的任务。 They collected DNA from patients who came into the clinic（诊所） for genetic（基因的） testing. Each sample is from a different and unrelated person. 他们收集了来诊所做基因测定病人的DNA。每个样本来自一个不
