Molecular mechanism of RNA modification

在每个活细胞中，称为核糖体的大型复杂机器合成所有蛋白质。这些蛋白质工厂由两种不同的生物分子组成，即蛋白质和RNA。RNA是类似于DNA的核酸，DNA是遗传物质。然而，与DNA相比，RNA不仅可以存储信息，而且它在细胞内也具有类似于蛋白质的功能。因此，RNA是在我们细胞中起作用的第三大生物分子。RNA在进行关键的生物化学作用中的重要性已经被最近的几个诺贝尔奖所认可。

In each living cell, large and complex machines called ribosomes synthesize all proteins. These protein factories consist themselves of two different biomolecules, namely proteins and RNAs. RNAs are nucleic acids resembling DNA, the genetic material. However in contrast to DNA, RNA can not only store information, but it has also functional roles within the cell similar to proteins. Thus, RNA is the third major biomolecule acting in our cells. The importance of RNA in carrying out crucial biochemical actions has been recognized by several recent Nobel prizes.
