Unfortunately, this includes DNA repair genes, so by having them silenced, errors during DNA replication don't get fixed.

不幸的是，DNA修复基因也可能被沉默，那么DNA复制过程中的错误将不能被修复。

For example, chemotherapy to a tumor or gene therapies to the tissue where gene repair needs to take place.

例如，对肿瘤进行化学疗法或对需要进行基因修复的组织进行基因疗法。
