遗传学的基本术语 1、性状( traits) 个个体从亲代传递到下一代的特性 2、基因(Gene): Physical and functional unit of heredity, which carries information from one generation to the next. In molecular terms, a gene is the entire dna sequence necessary for the synthesis of a functional polypeptide or RNA molecular. In addition to coding regions most genes also contain noncoding intervening sequences (introns )and transcription-control regins 携带从一代到下一代信息的遗传的物质单位和功能 单位。按分子术语讲,一个基因是合成一条有功能的多 肽或RNA分子所必须的完整的DNA序列。除了编码区外 大多数基因也包含非编码的间插序列和转录控制区。遗传学的基本术语 1、性状（traits） 一个个体从亲代传递到下一代的特性。 2、基因（Gene）: Physical and functional unit of heredity,which carries information from one generation to the next.In molecular terms, a gene is the entire DNA sequence necessary for the synthesis of a functional polypeptide or RNA molecular.
