For years, researchers described DNA and RNA as linear chains of four building blocks—the nucleotides A, G, C, and T for DNA; and A, G, C, and U for RNA. But these information molecules are much more ...

Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized ... These cytosine analogs ...

最新研究揭示，导致日晒伤急性反应的根源在于RNA受损，而非传统认知中的DNA破坏，为相关治疗提供了全新视角。 长期暴露在阳光下又缺乏足够保护，皮肤常会红肿灼痛，像一只即将上桌的龙虾。 传统观点认为，皮肤的炎症反应源于组织DNA受损后引发的一系列连锁效应。然而，最新针对小鼠和人类皮肤细胞的研究发现，晒伤的初始反应与以往预期截然不同。 “教科书告诉我们，晒伤是由DNA受损引起的细胞死亡和炎症，但这项研 ...
