The two ribbons symbolize the two phophate-sugar chains, and the horizonal rods the pairs of bases holding the chains together. The vertical line marks the fibre axis.

Chemical analysis of metalized DNA has made it quite clear that traditional models thermodynamics are insufficient to predict and control self-assembly in the context orthogonally-paired nucleotides. Recently, there been an increase reports Watson-Crick assembly wires nanostructures [1–4]. The ability add or remove pairing rules between nucleobases toward non-Watson-Crick, orthogonal, alters fu...

The traditional Watson-Crick base pairs in DNA may occasionally adopt a Hoogsteen conformation, with a different organization of hydrogen bonds. Previous crystal structures have shown that the Hoogsteen conformation is favored in alternating AT sequences of DNA. Here we present new data for a different sequence, d(ATTAAT)2, which is also found in the Hoogsteen conformation. Thus we demonstrate ...

We have compared the concentrations and total outputs of trypsin, amylase, and lipase secreted into the duodenum during secretin pancreozymin and Lundh Borgstrom tests in order to assess the relative intensity of pancreatic stimulation provided by these means. The mean concentration of trypsin, and the mean 10 minute total output of trypsin, amylase, and lipase after the meal (though less than ...
