摘要
真核生物核基因组内含有大量的DNA重复序列,在核基因组结构和功能研究中居于举足轻重的地位.本文主要介绍真核生物几类重要DNA重复序列的特点和用途,并对其在物种起源和进化、染色体分子指纹图谱绘制、分子标记辅助选择及染色体操作中的应用作了分析与介绍.
Repetitive DNA sequences form a large portion of eukaryote genomes, thus, they are important target in constructional and functional analysis of the eukaryote genomes. The classification, features and functional of several types of repetitive DNA were discussed in this review. Application of repetitive DNA sequences in study of evolution, chromosome and were also illustrated.
