近期《自然》杂志报道，人类和老鼠都有大约30 000条基因，其中约有80%的基因是完全一样的。人和老鼠大约共享有99%的类似基因，最有意思的是，人同样具有能“长尾巴的基因”。这项研究成果是两年前人类基因组排序成功以来科学研究领域的又一重大突破，有可能揭开人类患癌症和 Recent “Nature” magazine reported that humans and mice have about 30,000 genes, of which about 80% of the genes are exactly the same. About 99 percent of similar genes are shared between humans and mice. What is most interesting is that humans also have “long-tailed genes.” This research result is another major breakthrough in the field of scientific research since the successful sequencing of the human genome two years ago. It is possible to unravel the human cancer and
