早在 1990年 ,国际上就正式启动人类基因组计划。时隔 10年 ,于 2 0 0 0年 6月科学家宣布人的 2 2与 2 1号染色体的全序列测定已经相继完成 ,测序工作进入绘制完整序列图阶段。在 2 0 0 1年 2月 12日 ,中、美、日、德、法、英等 6国科学家和美国塞莱公司联合公布了更准确、更完 As early as 1990, the human genome project was officially launched in the world. After a lapse of 10 years, scientists announced in June 2000 that the complete sequencing of human chromosomes 2 2 and 2 1 has been completed one after another, and sequencing has entered the stage of drawing a complete sequence diagram. On February 12, 2001, scientists from six countries including China, the United States, Japan, Germany, France and Britain jointly announced with the United States Celeron more accurate and complete
