RNA reactor could have served as a precursor of life
(PhysOrg.com) -- Nobody knows quite how life originated on Earth, but most scientists agree that living cells did not abruptly appear from nonliving cells in a single step. Instead, there were probably a series ...

The language of RNA decoded: Study reveals new function for pseudogenes and noncoding RNAs
The central dogma of molecular biology, as proposed in 1970 by Francis Crick and James Watson, holds that genetic information is transferred from DNA to functional proteins by way of messenger RNA (mRNA). This suggests that ...

Nucleotide
Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA. Additionally, nucleotides play central roles in metabolism. In that capacity, they serve as sources of chemical energy (adenosine triphosphate and guanosine triphosphate), participate in cellular signaling (cyclic guanosine monophosphate and cyclic adenosine monophosphate), and are incorporated into important cofactors of enzymatic reactions (coenzyme A, flavin adenine dinucleotide, flavin mononucleotide, and nicotinamide adenine dinucleotide phosphate).
