随机扩增多态DNA (Random Amplified Polymorphic DNA ，简称RAPD)是J.Williams和J.Welsh两个研究小组于1990年同时提出的一种随机引物扩增，寻找多态DNA 片段的遗传标记技术，它是建立在PCR技术基础上，以随机的寡聚脱氧核苷酸作为PCR反应引物，对基因DNA 进行扩增而显示DNA 图谱和对物种进行亲缘关系、系统发育分子水平的鉴别，以及分子生物学 ...

分子诊断技术在检验医学的基础和临床研究中显示出强大的优势，例如，在乙型肝炎的诊断和治疗中，应用DNA定量技术为乙型肝炎的治疗和预后监测提供了重要依据，但近近不无症状乙型肝炎表面抗原携带者及乙型肝炎表面抗阴性者的人群中检出了前C终止密码子变异（G1896A）。研究表明，突变将导致乙型肝炎病毒继续复制，因此这一信息对于临床诊疗十分重要。又如庆大霉素等氨基糖苷类抗生素的毒副作用之一是诱发耳聋，且已证明线 ...

定位克隆（positoinal cloning），又称图位克隆（map-based clonig），1986年首先由剑桥大学的Alan Coulson提出。用该方法分离基因是根据功能基因在基因组中都有相对较稳定的基因座，在利用分离群体的遗传连锁分析或染色体异常将基因伫到染色体的1个具体位置的基础上，通过构建高密度的分子连锁图，找到与目的基因紧密连锁的分子标记，不断缩小候选区域进而克隆该基因，并单明 ...
