A new analysis of cancer genomes identifies a decrease in the mutation burden of exons, but not introns, as compared to expectation. This difference can be explained by preferential recruitment of the DNA mismatch repair machinery to a protein modification that marks exons.
一项对癌症基因组的新分析表明，与预期相比，外显子的突变负担减少，但内含子没有减少。这种差异可以通过 DNA 错配修复机制优先招募到标记外显子的蛋白质修饰来解释。
