| 摘 要： | 从染色体，分子，原子水平探讨了吸引和排斥与生命物质的关系。遗传和变异是生物界最基本的运动形式，它们的运动与吸引相互作用密切相关。吸引和排斥的相互作用生物大分子存在的基石，是细胞分裂，维持细胞结构和细胞内各种运动所必需的。同时，吸引排斥的作用还有基因调控，ＤＮＡ重组，突变和修复以及遗传工程中得到体现。

| Abstract: | The relation between attraction,exclusion and life motion is described at the level of chromosome ,molecule and atom.Heredity and variation are two basic motion forms of living nature.They are closely related with attraction and exclusion.Attraction and exclusion are the basis of big biological molecules.They are necessary for cell splitting,cell structure keeping and all kinds of motion in cells.At the same time,they also play an important role in gene control,DNA recombination,mutation and repair as well as genetic engineering. |
