Escalation of error catastrophe for enzymatic self-replicators [PDF]
It is a long-standing question in origin-of-life research whether the information content of replicating molecules can be maintained in the presence of replication errors.

Selective Nonenzymatic Formation of Biologically Common RNA Hairpins
Template‐free RNA loop‐closing ligation selectively generates RNA tetraloops that are prevalent in biology, as demonstrated by high‐throughput sequencing. Utilizing high‐yield overhang sequences enables the efficient assembly of functional RNAs. Abstract The prebiotic formation of RNA building blocks is well‐supported experimentally, yet the emergence ...

The effect of cytidine on the structure and function of an RNA ligase ribozyme
A cytidine-free ribozyme with RNA ligase activity was obtained by in vitro evolution, starting from a pool of random-sequence RNAs that contained only guanosine, adenosine, and uridine. This ribozyme contains 74 nt and catalyzes formation of a 3',5'-phosphodiester linkage with a catalytic rate of 0.016 min(-1).

The Implementation and Efficacy of Scientific Literature within an Introductory Biology Lecture Course:A Study in Pedagogy, Curricula, and Standards as They Apply to Post-Secondary Science Education [PDF]
The current study involved students enrolled in the Fall 2007 Biosc 0150 and Spring 2008 Biosc 0160 lecture sections of a single Faculty member. Most students were incoming freshmen, and their prior exposure to the natural sciences varied.

Mini-ribozymes and freezing environment: a new scenario for the early RNA world
International audienceThe RNA World hypothesis states that the present-day life, which is based on DNA genomes and protein enzymes, was preceded by a simpler life form based primarily on RNA.

Continual reproduction of self-assembling oligotriazole peptide nanomaterials. [PDF]
Autocatalytic chemical reactions, whereby a molecule is able to catalyze its own formation from a set of precursors, mimic nature's ability to generate identical copies of relevant biomolecules, and are thought to have been crucial for the origin of life.

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
