The G-->A mutation gives rise to HCV RNA molecules that, in conjunction with mutations in the HCV non-structural region, such as the G(2042)C/R mutations, possess greater efficiency of transduction and/or replication. These RNA molecules when transfected in a cell line are useful for ...
Dutch researchers have seen parasitic behaviour that’s usually associated with life emerge in a system of non-biological self-replicating molecules for the first time. The finding offers clues to how life evolved as well as how synthetic life could be made out of simple self-replicating c...
Self-replicating molecules provide a simple model that allows us to capture the fundamental processes that occur in species formation. We have been able to monitor in real time and at a molecular level the diversification of self-replicating molecules into two distinct sets that compete for two ...
First recorded in 1955–60 Discover More Example Sentences Curiously, of the 4.9 billion reactions generated, only hundreds of reaction cycles could be called "self-replicating," which means that the molecules produce additional copies of themselves. ...

Question: Origin of Life: How did the first self-replicating molecules originate on Earth, and what were the conditions that allowed for the transition from simple organic molecules to complex life forms?Consciousness: What are the biological and neurol...
MIills, P'eterson, aind Spiegelman5 reported experiments of this nature desigiied to select nmolecules that could replicate faster than the originial viral RNA. Duriiig the course of the serial transfers involved, varianits of decreasing length made their appearance sequentially. The mutant ...
By combining the self-replication reaction with the expression of luciferase DNA, as low as 1400 T7RP molecules are detectable. Furthermore, the T7RP is biotinylated, complexed with streptavidin and used for antigen quantification in a microtiter well-based assay with high sensitivity and ...
said jeffrey bada, a chemist at the scripps institution of oceanography, who was not involved with the work. it shows that rna molecules "could have carried out their replication in the total absence" of the more sophisticated biological machinery that life now possesses. "this is a nice ...
