We expect that this approach will get us closer to understanding the balance between gene content and gene regulation in the question of human-chimp diversity.
我们希望这种方法可以使我们了解在基因多态性中基因结构和基因调节的平衡。
We thus hypothesized that tumor diversity also holds true at the gene expression level.
我们因此假设肿瘤多样化在基因表达层面也成立。
