Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are ...

Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...
