| 1. | Tandem repeats play a variety of roles in gene expression , regulation and evolution , and are ideal marker in genetic mapping . further more , the techniqe of dna fingerprinting based on the polymorphism of tandem repeat is now widely used in various fields such as medical jurisprudence , etc . the more eye - catching discovery is , in recent years , that some genetic diseases are related with certain trinucleotide repeats
串联重复在基因表达、调控和遗传等方面起着十分重要的作用,同时它因具有高度多态性,已成为基因组遗传图谱和物理图谱的理想界标,另外以串联重复为基础的“ dna指纹技术”在法医学等领域广泛应用。 |
