Nucleic Acids Research, 2013 We have determined the three-dimensional (3D) structure of DNA duplex that includes tandem HgII-mediated T–T base pairs (thymine–HgII–thymine, T–HgII–T) with NMR spectroscopy in solution.

Termination Proofs in the Dependency Pair Framework May Induce Multiple Recursive Derivational Complexity [PDF]
, 2011 We study the derivational complexity of rewrite systems whose termination is provable in the dependency pair framework using the processors for reduction pairs, dependency graphs, or the subterm criterion. We show that the derivational complexity of such

Base pair opening within B-DNA: free energy pathways for GC and AT pairs from umbrella sampling simulations. [PDF]
, 2003 The conformational pathways and the free energy variations for base opening into the major and minor grooves of a B-DNA duplex are studied using umbrella sampling molecular dynamics simulations. We compare both GC and AT base pair opening within a double-

Reversibly locked thionucleobase pairs in DNA to study base flipping enzymes
Beilstein Journal of Organic Chemistry, 2014 Covalently interstrand cross-linked DNA is an interesting tool to study DNA binding proteins that locally open up the DNA duplex by flipping single bases out of the DNA helix or melting whole stretches of base pairs to perform their function.

Influence of supercoiling on the disruption of dsDNA
, 2004 We propose that supercoiling energizes double-stranded DNA (dsDNA) so as to facilitate thermal fluctuations to an unzipped state. We support this with a model of two elastic rods coupled via forces that represent base pair interactions.

A base pair resolution map of nucleosome positions in yeast
Nature, 2012 The exact positions of nucleosomes along genomic DNA can influence many aspects of chromosome function. However, existing methods for mapping nucleosomes do not provide the necessary single-base-pair accuracy to determine these positions. Here we develop

Estimating Exceptionally Rare Germline and Somatic Mutation Frequencies via Next Generation Sequencing. [PDF]
PLoS ONE, 2016 We used targeted next generation deep-sequencing (Safe Sequencing System) to measure ultra-rare de novo mutation frequencies in the human male germline by attaching a unique identifier code to each target DNA molecule. Segments from three different human

The Influence of Neighboring Base Pairs upon Base-Pair Substitution Mutation Rates [PDF]
Proceedings of the National Academy of Sciences, 1971 The 2-aminopurine-induced transition, A·T → G·C, was studied at particular sites in bacteriophage T4 as a function of the nearby base-pair composition of the DNA. Changing a base pair changed the transition rate at the adjacent base pair up to 23-fold, and at the next base pair by a lesser amount.

Significance of authenticity in meat and meat products in Iran
Iranian Journal of Health, Safety and Environment, 2014 The Authenticity of meat products is very important for religious and health reasons in Iran. According to legislation in Iran, the consumption and importation of pork, horse, donkey and cat products should be banned.
