UMD researchers have discovered key mechanisms in gene regulation that could improve the design of RNA-based medicines.
1958年,弗朗西斯・克里克提出了中心法则,提出遗传信息从 DNA 转录为 RNA,再经翻译指导蛋白质合成,随后蛋白质参与生命活动这一流程,看似一气呵成,实则存在问题。 若仔细观察,便会发觉此流程不够简洁,RNA 的存在略显累赘。毕竟,越简单的系统往往越高效、越易实现,繁琐的系统则耗能多且不易形成。 从结构看,RNA 与 DNA ...

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.
科技日报讯 (记者张佳欣)多年来,教科书和皮肤科医生一直告诉人们,晒伤主要与DNA损伤有关。然而,发表在《分子细胞》杂志上的一项新研究表明,实际上,是RNA损伤引发了晒伤时的急性炎症反应。
A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed ...
