NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

Although answers to these profound questions are not yet completely known, it seems very probable that both DNA and RNA viruses target the same cellular structure, which might reflect a mechanism ...

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers ...

Textbooks need to be rewritten: RNA, not DNA, is the main cause of acute sunburn. ScienceDaily . Retrieved February 8, 2025 from www.sciencedaily.com / releases / 2025 / 01 / 250117112413.htm ...

Recent research reveals that DNA and RNA epigenetics, previously studied as independent systems, actually function as a complementary regulatory network. This dual mechanism enables precise gene ...

From there, DNA or RNA provides the instructions for cells ... McCoy's team also hopes to find bits of water trapped in the crystalline structure of Bennu's mineral grains and trace that water's ...

By treating DNA as a language, Brian Hie’s “ChatGPT for genomes” could pick up patterns that humans can’t see, accelerating ...

The redness, inflammation, and pain of sunburn may stem from damage to RNA, not DNA. “Sunburn damages the DNA, leading to cell death and inflammation. So the textbooks say,” said Assistant ...

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 ...

Enzymes made of RNA are called "ribozymes." A group of researchers led by Professor Claudia Höbartner at the University of Würburg (JMU) has now uncovered the three-dimensional structure of a ...
