基因概念的思想渊源及其历史发展

从科学角度追溯基因概念渊源及其历史发展具有现实意义,论述基因概念蕴育以及从Mendel假设的遗传因子、Johannsen抽象的基因,到Sutton,Margan等把基因着落到染色体上,迎来生物学上第二次革命的到来.在DNA结构模型的基础上,研究者们对基因概念进行了修正与补充.说明任何"最科学"的概念都不可能是凝固的,绝对不变的.科学概念的科学性和生命力就在于它能随实践和认识的发展不断发展、深化、修正和更新.

The Thought Drigin of the Gene Conception

From the aspect of scientifically looking back at the thought origin of the gene conception and its realistic significance in histovical development ,this article expounds the gene conception content and analyses the course of biological development ,from assumed factors by Mendel,abstract genes by Johannsen to genes on chromosonces by Sutton,Morgan and so on,and now to the second revolution in biology.Based on DNA formation model,the researchers have revised and supplemented the gene conception,pointing out that any "most scientific" theory cannot be fixed and unchangeable .Development,profundity,revision and renewal are the scientificity and vitality of the scientific conception.
