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. In addition, nucleotides participate in cellular signaling (cGMP and cAMP), and are incorporated into important cofactors of enzymatic reactions (coenzyme A, FAD, FMN, and NADP+). Nucleotide derivatives such as the nucleoside triphosphates play central roles in metabolism, in which capacity they serve as sources of chemical energy (ATP and GTP).
