Chemists recreate how RNA might have reproduced for first time
DNA
Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life. Scientists believe that, in the earliest life forms, genetic material would have been carried and replicated by strands of RNA, before DNA and proteins later emerged and took over. Yet getting strands of RNA to replicate in the lab in a simple way – i.e., that plausibly could have occurred at the outset of
