Homologous degree of repetitiveDNA sequences among different species reveals their evolutionary relationship in a certain degree.
物种间重复序列的同源程度可以有效地反映它们亲缘关系的远近。

The oligonucleotide probe LZF-I, which is synthesized by us, can form thehybrid molecules with the simple repetitiveDNA of three species of fishes.
我们自己制备的LZF—I探针，能与鱼类基因组DNA中的简单重复序列杂交形成杂交分子。

The difference is the amount of DNA that could be supported in the nucleus, not as repetitive copies of the same old genes, but as the raw material for new evolution.
