Origin of Information Encoding in Nucleic Acids through a Dissipation-Replication Relation [PDF]
Ultraviolet light incident on organic material can initiate its spontaneous dissipative structuring into chromophores which can then catalyze their own replication. This may have been the case for one of the most ancient of all chromophores dissipating the Archean UVC photon flux, the nucleic acids.

Locked nucleic acid: tighter is different [PDF]
This viewpoint briefly reviews the impact of Locked Nucleic Acid (LNA) oligonucleotides, first described in a ChemComm paper in 1998. A number of unique applications in oligonucleotide biotechnology have been made possible by the high binding affinity ...

Absolute quantification of real-time PCR data with stage signal difference analysis [PDF]
Real-time PCR, or Real-time Quantitative PCR (qPCR) is an effective approach to quantify nucleic acid samples. Given the complicated reaction system along with thermal cycles, there has been long-term confusion on accurately calculating the initial nucleic acid amounts from the fluorescence signals.

Since the discovery of the structure of the DNA double helix in 1953 by Watson and Crick [1], we know that DNA is of critical importance, carrying the genetic information for all living organisms. Only a few years later appeared the first reports on the chemical synthesis of oligonucleotides with a natural 3'-5' phosphodiester linker by Michelsen and ...

Conformational switches control early maturation of the eukaryotic small ribosomal subunit
Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.

Rigid Base Biasing in Molecular Dynamics enables enhanced sampling of DNA conformations [PDF]
All-atom simulations have become increasingly popular to study conformational and dynamical properties of nucleic acids as they are accurate and provide high spatial and time resolutions. This high resolution however comes at a heavy computational cost and within the time scales of simulations nucleic acids weakly fluctuate around their ideal structure

Velocity and processivity of helicase unwinding of double-stranded nucleic acids [PDF]
Helicases are molecular motors which unwind double-stranded nucleic acids (dsNA) in cells. Many helicases move with directional bias on single-stranded (ss) nucleic acids, and couple their directional translocation to strand separation. A model of the coupling between translocation and unwinding uses an interaction potential to represent passive and ...
