The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. In reality, there is much more to the RNA story. However ...

RNA is often compared to a copy from a reference book, or a template, because it carries the same information as its DNA template but is not used for long-term storage. Each ribonucleotide base ...

RNA, which carries the information encoded by DNA to the places where it is needed, is amazingly diverse and dynamic. RNA is processed and modified through natural biological pathways, giving rise to ...

Kossel isolated cytosine from calf thymus tissues and found that it was a component of nucleic acids. This discovery, along with the identification of other nitrogenous bases, laid the foundation for ...

The other consists of an RNA guide that leads the scalpel to the precise nucleotides—the chemical letters of DNA—it has been sent to cut. (Researchers rarely include the term “Cas9” in ...

科技日报北京9月1日电 （记者张梦然）DNA因其标志性的双螺旋结构而广为人知。但澳大利亚加文医学研究所科学家发现，人类基因组还含有超过5万个不寻常的结状DNA结构，称为i-基序。最新一期《EMBO》杂志发表了这些独特DNA结构的第一张综合图谱，揭示了它们在 ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...

Unlike gene editing technologies, which make permanent changes to DNA, RNA therapies offer a temporary but highly targeted approach. However, one major challenge is RNAs do not last long in the ...
