This transition likely involved the formation of a lipid membrane—perhaps spontaneously forming around RNA and other molecules—creating the first protocells.

这种转变可能涉及脂质膜的形成（可能在 RNA 和其他分子周围自发形成），从而产生了第一个原始细胞。

As these protocells evolved, DNA took over as the primary information storage molecule, proteins assumed the role of primary catalysts, and RNA served as the messenger between them.

随着这些原始细胞的进化，DNA 成为主要的信息存储分子，蛋白质承担了主要催化剂的作用，而 RNA 则充当了它们之间的信使。
