这种小核糖核酸分子没有参与合成蛋白质，而是附着在信使核糖核酸上(如图)，来消灭它们。
Instead of synthesizing proteins, this tiny RNA molecule latched onto messenger RNAs (chart), causing their destruction.
此外，因为小分子核糖核酸的构造既小又简单，所以可以制造核糖核酸，把它当作研究工具来使用。
Moreover, because microRNAs are so small and simple in structure, they can be manufactured for use as research tools.
早期研究发现小分子核糖核酸还可以促进干细胞的产生。
Early studies suggest that microRNAs can also boost the production of stem cells in culture.
小分子核糖核酸可以用来封闭人体细胞，使之免受致病病毒的侵扰，或者使病毒丧失侵入细胞的能力。
MicroRNAs could be used to seal off human cells from disease-causing viruses, or to disable viruses that gain entry.
与美国N C B I的网上基因数据库比较，发现这3 者又与萨尔瓦多等其他5 个间日疟原虫不同地理株的小亚单位核糖体核糖核酸相应基因片段完全一致。
Compared with data got from NCBI genbank, targeted SSUrRNA gene sequences of above mentioned 3 isolates were the same as those of other 5 different P. vivax geographical isolates .
这种发夹状的结构被分成小分子RNA段，然后与另外一组染色体共同产生影响，然后沉默另外一种带有互补序列的信息核糖核酸。
The hairpin structure is diced into a microRNA segment that works with another complex to disable other messenger RNAs with complementary sequences.
