Components of the cells that are sensitive to dryness, like DNA, proteins, and membranes, get trapped in this matrix.

对干燥敏感的细胞成分，如 DNA、蛋白质和细胞膜，会被困在这种基质中。

The most common type is Non-Homologous End Joining where a protein complex called DNA protein kinase begins by binding to each end of the broken DNA.

最常见的类型是非同源末端连接：一个叫做DNA蛋白激酶的蛋白质复合体首先会结合到断裂的DNA末端。

Because of their instability, free radicals are on the hunt for more electrons and will take them from things like DNA, proteins, and fats—reacting with those molecules and damaging them in the process.

由于这些自由基的不稳定性，它们还会继续寻找更多电子，将它们和 DNA、蛋白质和脂肪一类的物质分离，与分子反应，逐步破坏分子。
