摘要
生命科学研究的进展日新月异。科技信息的交流和成果的沟通是开展科学研究的支柱之一。本文概述了分子生物学、植物细胞分化以及基因导入等三个相互渗透的学科进展的动态,以启发我们如何根据自己的国情合理布局研究课题,有效使用科研经费。分子生物学是研究组成生物本身的重要物质:核酸、蛋白质和酶的结构和功能,合成和代谢,表达和调控以及它们之间的相互作用,以此来揭示生命的本质,是生命科学研究的前沿和核心。细胞分化是生物发育的依据,它始终作为生命之谜为世人瞩目。归根结底是基因表达的调控;外源基因的导入则是研究遗传工程的重要手段,只有外源基因被受体整合后,才有可能实现其获得性状的表达和遗传。
The exchanges of scientific information flay animportant role in life sciences, including molecular biology, cell differentiotion, exogenous gene introduction and so on, in order to make plans for the studies according to our conditions and needs.
The aims of molecular biology are to study the structure and fundtion of nucleic acids, proteins and enzymes to revaal the nature of life activities, cell differetiation is the foudation of life genesis and individual development and the key to the door of life mysteries. Exogenous gene in tro duction is the main method used in genetic engineering, but only after the exogenous genes are integrated to the receptors genetic metarials, the expression and heredity of the acquired characters may come true.
