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 ...

RNA is generally single-stranded, as DNA is transcribed by RNA polymerases into mRNA (messenger RNA), which is read by ribosomes to generate protein (translation). Biologically active RNAs ...
