A team at UT Southwestern Medical Center has identified a structural trick that lets viruses translate their genetic code inside human cells, even when that code is riddled with “bad” codons the host ...

A study published this week in the journal Nature Astronomy presents evidence that the asteroid Ryugu contains all five of the nucleotide bases that make up the genetic code. That includes the ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...
