因此，在最小基因集合的第一版本中包含的一些基因，基于一个有限基因组比较事实上可能是非必须的。

Thus, some of the genes that were included in the first version of the minimal gene set, based on a limited genome comparison, could be, in fact, dispensable.

尽管目前已经有很多工作利用基因表达谱数据以及一些其他的先验知识来寻找那些与肿瘤相关的基因集合，但还是没有一个恰当的基因集合的统计学方法。

Although there has been much work focused on searching gene sets using gene expression data or other prior information, proper statistical testing of the gene sets is still an open question.

每一个探针与一种特定基因的RNA绑定——它含有了一整套化学物质和基质的集合。

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