人类的遗传物质是DNA,它的总和就是人类基因组,由大约30亿碱基对组成,分布在人体细胞核的46条染色体中。举世瞩目的“人类基因组计划”的核心,就是测定蕴涵着生命根本奥秘的人类基因组的全部DNA序列。2000年6月26日,包括我国在内的参与该项计划的科学家,向全世界正式宣布:人类基因组草图完成。不可否认,人类基因组中蕴涵着人类生、老、病、死的绝大多数遗传信息,它的破译必将为疾病的诊断、新药物的研制和新疗法的探索带来革命性的发展。然而,随着它的破译也带来了一些令人不安的信息。尽管在已经开始的人类基因组多样性的研究中发现人与人之间的差别不到千分之一,但在已经发现的基因中,确实
Human genetic material is DNA. Its sum is the human genome. It consists of about 3 billion base pairs and is distributed on the 46 chromosomes of the human nucleus. The core of the “Human Genome Project” that attracts worldwide attention is the determination of the entire DNA sequence of the human genome that contains the fundamental mysteries of life. On June 26, 2000, scientists involved in the project, including my country, formally announced to the world that the draft of the human genome was completed. It is undeniable that the human genome contains the vast majority of genetic information about human life, aging, disease, and death. Its deciphering will certainly bring about revolutionary development in the diagnosis of diseases, the development of new drugs, and the exploration of new therapies. However, as it was deciphered, it also brought some disturbing information. Although less than 1 in 1,000 human-human differences have been found in the study of human genome diversity that has already begun, it is true that
