第一个层面是研究物质结构及其运动规律的物质科学 ,由此将深化人们对物质世界和宇宙起源与演化的认识。第二个层面是生命科学。2 0世纪末 ,人类基因组全部测序工作基本完成 ,预示着新世纪生命科学必将酝酿着新的突破 ,将引发对解读基因密码规律的探索 ,从而使人类在分子水平上 The first level is the material science that studies the structure of matter and its laws of motion, thereby deepening our understanding of the material world and the origins and evolution of the universe. The second level is life sciences. At the end of the 20th century, sequencing of all the human genomes was basically completed, which indicates that new breakthroughs are bound to be brewed in the life sciences in the new century and will lead to the exploration of the law of reading the genetic code so that human beings at the molecular level
