The question of how life could have emerged is one of the most long-standing mysteries in science. In a new study, the ...

Of the 64 codons, only 61 code for amino acids and the remaining three codons are STOP codons that signal the end or termination of translation. UAA, UAG, and UGA are the three RNA STOP codons and ...

This observation provided a plausible reason for the previously unexplained trend of selective aminoacylation of L-amino acids in RNA minihelices. The insights presented in the paper have brought ...

Chemists have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth -- a key process in the origin of life.

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have ...

Similarly, on fusing an L-histidine-binding RNA sequence to the ribozyme, they noted an increase in ligase activity at increasing concentrations of histidine (a key amino acid). Notably ...

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). TComparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases ...
