继英国科学家克隆羊“多利”诞生后 ,生命科学领域紧接着又一项以确定人类基因的结构和功能、表达和调控的“人类基因组计划”(ＨＧＰ)正在各大国相继地展开[1～ 4] 。今天人类 3× 1 0 9个核苷酸全序列中约有 5 0 0 0个基因已被测序 ,同时随着技术及测序仪器的更新 ,每年测序
Following the birth of Dolly, a British clone of scientists, another Human Genome Project (HGP) in the field of life science to determine the structure and function, expression and regulation of human genes is being carried out one after another in major countries [1-4 ]. Today, about 50000 genes have been sequenced in the entire 3 × 1 0 9 nucleotide sequence of human beings. At the same time, as the technology and sequencing equipment are updated, they are sequenced annually
