Acetes chinensis is an economically important shrimp that belongs to the Sergestidae family; following fermentation, A. chinensis′ economic value, however, is low in China, and much of the catch in Ch...
Genetic Diversity of mtDNA D-loop and Maternal Origin of Three Chinese Native Horse Breeds
Chinese Western Native Horses Mitochondrial DNA D-loop Genetic Diversity Maternal Origin
2016/5/10
In order to protect the genetic resource of native horse breeds, the genetic diversity of mitochondrial DNA (mtDNA) D-loop of three native horse breeds in western China were investigated. Forty-three ...
This work faces the problem of the origin of the logarithmic character of the Gompertzian growth. We show that the macroscopic, deterministic Gompertz equation describes the evolution from the initial...

摘要
1953年Watson & Crick 对于DNA双螺旋结构模型的提出及对其遗传机理的解释,标志着现代分子生物学的诞生。其后短短50年的时间里,分子生物学在各个学科之间广泛渗透,相互促进,不断深入和发展。在以研究人类的起源和进化为首要任务的人类学领域,由于现代分子生物学理论和方法的应用,诞生了分子人类学这一全新的结合型分支学科,为人类学的发展提供了科学可信的研究方法和具发展前景的研究方向。...
“基因”一词的由来The Origin of the Term “GENE”
基因 泛生子
2007/12/7
摘要1909年,约翰森创造“基因”(gene)一词作为遗传单位的名称。该词是由德?弗里斯创造的“泛生子”(pangene)一词缩短而成的,而“泛生子”一词则衍生于达尔文提出的“泛生论”(theory of pangenesis)。约翰森的这一创造堪称“推陈出新”的典范。
