The first peptides: the evolutionary transition between prebiotic amino acids and early proteins [PDF]
The issues we attempt to tackle here are what the first peptides did look like when they emerged on the primitive earth, and what simple catalytic activities they fulfilled.

Witnessing the Evolution of RNA [PDF]
The RNA World theory postulates that at a certain point around 4 billion years ago during an RNA World period, a molecule, possibly RNA, developed the ability to self-replicate via polymerization.

Correcting pervasive errors in RNA crystallography through enumerative structure prediction
Three-dimensional RNA models fitted into crystallographic density maps exhibit pervasive conformational ambiguities, geometric errors and steric clashes. To address these problems, we present enumerative real-space refinement assisted by electron density

The nonenzymatic template-directed ligation of oligonucleotides
International audienceThe nonenzymatic template-directed ligation of oligonucleotides containing 2',3'-cyclic phosphate was investigated in the presence of divalent cations. Ligation of the oligonucleotides readily occurred in the presence of Mg2+, Mn2+,
