分子生物学是最近十八年来,生物科学中一门新兴的学科。它标志着生物科学从整体器官和组织水平的宏观研究,进入到亚细胞结构和分子水平的微观研究。分子生物学的核心是研究生物高分子特别是核酸,蛋白质的结构和生物功能。它的领域包括细胞核与膜的结构和功能,遗传的物质基础,信息传递,细胞的分裂、生长与代谢控制等一系列生命现象。
Molecular biology is an emerging discipline in biological sciences in the past 18 years. It marks the macroscopic study of the biological sciences from the level of whole organs and tissues, into the microscopic studies of subcellular structures and molecular levels. The core of molecular biology is to study the structure and biological functions of biopolymers, especially nucleic acids and proteins. Its fields include the structure and function of the nucleus and membrane, the material basis of heredity, information transmission, cell division, growth and metabolic control and a series of life phenomena.
