| 摘 要： | 亲代印迹是指来自于父母双方的同源染色体或等位基因 ,在功能上存在差异 ,当其传给子代时 ,基因表达活性不同。研究表明 ,亲代印迹是一种特殊的“后成修饰”机制 ,甲基化是“印迹”修饰最可能的机制。亲代印迹不仅与人类疾病、哺乳类发育有关系 ,而且它对“中心法则”的发展及进化论的研究均具有重大意义

| Abstract: | Parental imprinting is that the homologus chromosomes or alleles are different in functions,so the gene expressing activities are different when they transfer to filial generations.The researches prove that the parental imprinting is a special post-modification mechanism,and methyation is the most possible mechanism of imprinting modification.Parental imprinting not only is related to the human diseases and the development of mammal,but also is important to the development of central dogoma and the research of theory of evolution. |
