在黄鳝二价染色体上，运用地高辛配基标记的随机引物原位DNA合成技术诱导出了明暗相间、基本稳定且类似于R带的带状结构。本文对该结果进行了较详细的分析和讨论。

The dark bands alternating with light bands , relatively stable and R-band-like structure was showed on the pachytene bivalents of Rice-fleld eel ( Monoplerus albus Zuiew ) by using the random-primed in situ digoxigenin-labelled DNA synthesis technique , and the results were analysed and discussed in detail .
