RNA that nearly self-replicates offers new clues to life’s origins
A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early ...
Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...
Liquid brine veins, where RNA molecules can replicate, surround solid ice crystals in water ice, as seen with an electron microscope. Chemists at UCL and the MRC Laboratory of Molecular Biology have ...
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 ...
Cells use the genetic information contained in DNA to generate proteins, which carry out many of the processes of life. RNA is the intermediate molecule; it is transcribed from DNA, then edited, ...
HIV replication in the human body requires that specific viral RNAs be packaged into progeny virus particles. A new study has found how a small difference in the RNA sequence can allow the viral RNA ...
