基因是细胞内DNA分子上具有遗传效应的特定核苷酸序列的总称，是具有遗传效应的DNA分子片段。基因控制蛋白质合成，是不同物种以及同一物种的不同个体表现出不同的性状的根本原因，即所谓"种瓜得瓜，种豆得豆"，"一母生九子，九子各不同"。基因通过DNA复制及细胞分裂把遗传信息传递给下一代，并通过控制蛋白质的合成使遗传信息得到表达。 基因克隆技术包括了一系列技术，它大 ...

功能克隆（funetional cloning）是利用疾病已知的遗传损伤而引起的生化功能如蛋白质基酸缺陷的信息，进行基因定位，进而克隆 该致病基因。以进行的基因克隆 大都是预先测知疾病基因的编码蛋白质，利用其mRNA反转录成cDNA，再用cDNA作探针，从人基因组中“约”出基因本身。然而，绝大多数遗传病的基因产物不明，就无法用功能克隆策略进行基因克隆。 ...
