撰文丨王聪编辑丨王多鱼排版丨水成文众所周知，根据中心法则，DNA转录为mRNA，mRNA再翻译为蛋白质，mRNA的降解速率是每个基因产生的蛋白质的数量的主要决定因素，而这又会影响细胞功能。例如，对于mRNA疫苗，mRNA存在更长时间会产生更多蛋白质， ...

Ⅰ型内含子是含量最为丰富的拥有自剪接活性的内含子，数量已经超过 20000 个，广泛分布于自然界中。 从细菌、真菌、原生生物及植物，到细胞核、线粒体及叶绿体，再到 mRNA、tRNA 及 rRNA 基因，你都可以发现它们的存在。

The link seems to be another class of small molecules known as short non-coding RNAs, or simply sncRNAs, whose levels can change in response to infection or environmental pollutants.

德克萨斯大学西南医学中心研究人员的一项新研究表明，转移RNA （tRNA）是一种以读取构建蛋白指令而闻名的遗传分子，在调节这些指令在细胞中持续的时间方面也起着关键作用。发表在《Science》杂志上的这一发现，扩大了对信使RNA （mRNA）降解时间的理解，信使RNA是控制基因活动的重要机制，最终可能有可能导致肥胖、癌症和其他健康状况的新疗法。

The global organization of the tRNA structure is highly conserved in all forms of life. Prominent features of the tRNA structure, as shown in the figure, include: an acceptor stem with the CCA ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...
