基因 基因
  • 基因一词来自希腊语,意思为“生”。是指携带有遗传信息的DNA序列,是控制性状的基本遗传单位,亦即一段具有功能性的DNA序列。基因通过指导蛋白质的合成来表現所携带的遗传信息,从而控制生物个体的性状(差異)表现。人類約有兩萬至兩萬五千個基因。
  • 染色体在体细胞中是成对存在的,每条染色体上都带有一定数量的基因。一个基因在细胞有丝分裂时有两个对列的位点,称为等位基因,分别来自父与母。依所攜帶性状的表現,又可分为显性基因和隐性基因。
  • 一般来说,同一生物体中的每个细胞體都含有相同的基因,但并不是每个细胞中的所有基因携带的遗传信息都会被表現出来。職司不同功能的細胞中,活化而表現的基因也不同。
