激活基因表达或使基因表达失活的化学诱导系统在确定基因功能及植物生物技术中有许多潜在的应用。
Chemically inducible systems that activate or inactivate gene expression have many potential applications in the determination of gene function and in plant biotechnology.
这种现象主要在印迹基因和X染色体失活区域看到，这些区域中的启动子区的DNA甲基化导致了基因表达的抑制。
This phenomenon is mostly seen in imprinted genes and X-chromosome inactivation where DNA methylation of promoter regions leads to repression of gene expression.
探讨这些基因逃避X失活的机制有助于理解X染色体失活是如何对基因表达进行调控的。
Study on the mechanisms of 'escape' is helpful to the understanding of gene regulation by X inactivation.
