Archaeal histone distribution is associated with archaeal genome base composition.
A subpopulation of Archaea possesses histones, which are similar to eukaryotic histones H3 and H4. However, archaeal histones are smaller than H3 and H4, and are not post-translationally modified.

Global modelling of H2 mixing ratios and isotopic compositions with the TM5 model [PDF]
The isotopic composition of molecular hydrogen (H2) contains independent information for constraining the global H2 budget. To explore this, we have implemented hydrogen sources and sinks, including their isotopic composition, into the global chemistry ...

FeS corrosion products formation and hydrogen uptake in a sour environment for quenched & tempered steel [PDF]
Surface corrosion product formation is one of the important factors affecting the corrosion rate and hydrogen uptake in a H2S environment. However, it is still unclear how the base material composition will affect the corrosion products that are ...

BackgroundThe polyadenylation of RNA is critical for gene functioning, but the conserved sequence motifs (often called signal or signature motifs), motif locations and abundances, and base composition patterns around mRNA polyadenylation [poly(A)] sites ...
