If a gene is active, the RNA in the sample binds to the complementarygene fragment on the slide, and can be detected under ultraviolet light as a coloured dot.
He concluded that the assays for mutations in either gene should be considered complementary tests, reflecting mutations that occur through different mechanisms.
他还指出,对于任何一种基因突变的化验分析都应作为补充试验,以此来反映不同机制所产生的变异。

Each probe binds to the RNA of a specific gene-the one that contains a complementary set of chemical units, or bases.
