Unlocking the Human Genome (基因组)
1．A．project to unlock secrets—what scientist could resist that challenge This is what many scientists are doing as they work on the Human Genome Project. The aim of the project is to decode (破译) all of the some 100,000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding.
2．DNA．is the substance found in the chromosomes (染色体) of a cell. A chromosome is a chain of genes. Each gene carries a piece of genetic information. At any one moment in a cell, thousands of genes are turned on and off to produce proteins (蛋白质). The challenge for scientists is to find out what role each gene plays in protein production. At some point this decoding will be complete. Then scientists will have a map of an ideal genome, or a picture of the total genetic nature of a human being. The ideal genome is called a consensus (交感) genome. Everything works well in a consensus genome.

A. 含有一个生物体生存、发育、活动和繁殖所需要的全部遗传信息的整套核酸
B. 包括编码蛋白质的结构基因
C. 也包括复制和砖录的调控信号
D. 还包括一些功能尚不清楚的区域
[填空题]结构基因组学是通过______的实施来完成的。以全基因组测序为目标的基因结构研究，弄清基因组中全部基因的位置和结构，为基因功能的研究奠定基础。其目的是建立高分辨的______、______、______和______。
[简答题]以人类基因组和拟南芥基因组为例说明你对生物基因组全序列测定工作的科学意义的认识。
[简答题]水稻是禾本科植物中基因组最小的物种，目前已完成基因组草图，而禾本科其他作物都未有完整基因组测序资料。现在水稻中克隆了一个矮秆基因，如何由此出发，克隆大麦中的矮秆基因构建大麦的基因组DNA文库；把水稻的矮秆基因标记后作为探针筛选该文库。
