An extreme level of DNA sequence polymorphism, the basis of DNA fingerprinting, was first demonstrated using genome derived cloned probes. Subsequently, it was shown that DNA fingerprinting can also be carried out using short synthetic oligodeoxyribonucleotide probes specific for simple repetitive sequences. Further, in addition to radioactively labeled probes, non-radioactive oligonucleotides generate equally informative hybridization patterns. We discuss the development in the area of DNA fingerprinting and its future scope with respect to plant, animal and the human DNA.
作为DNA指纹识别基础的极高水平的DNA序列多态性,最初是使用基因组衍生的克隆探针来证明的。随后,研究表明,DNA指纹识别也可以使用针对简单重复序列的短合成寡脱氧核糖核苷酸探针来进行。此外,除了放射性标记的探针外,非放射性寡核苷酸也能产生同样具有信息性的杂交模式。我们将讨论DNA指纹识别领域的发展及其在植物、动物和人类DNA方面的未来前景。
