Scientists have long pondered the beginnings of life on Earth. One theory is that RNA, which is ubiquitous across all domains of life, played a central role in early life. […]

Template-Directed Replication and Chiral Resolution during Wet–Dry Cycling in Hydrothermal Pools
The commonly supposed template-based format for RNA self-replication requires both duplex assembly and disassembly.
