DOI: 10.1002/bip.23397
Abstract: We present a new structure of a DNA dodecamer obtained in the presence of Ni2+ ions. The DNA forms Ni‐guanine cross‐links between neighboring molecules. Our results show that an adequate dosage of Ni2+ may help… read more here.

DOI: 10.1007/s11229-017-1339-6
Abstract: In his late years, Thomas Kuhn became interested in the process of scientific specialization, which does not seem to possess the destructive element that is characteristic of scientific revolutions. It therefore makes sense to investigate… read more here.

DOI: 10.1016/j.ica.2017.02.017
Abstract: Abstract New bisphosphoramides (having phenyl (EDAPOPh 2 ) and ethoxy (EDADEP) substituents attached to phosphoryl groups bridged with ethylenediamine spacer) are synthesized and structurally characterized by spectroscopic techniques as well as elemental analysis. The molecular… read more here.

DOI: 10.1038/d41586-019-02554-z
Abstract: In the early 1950s, the identity of genetic material was still a matter of debate. The discovery of the helical structure of double-stranded DNA settled the matter — and changed biology forever. The discovery of… read more here.

DOI: 10.1093/nar/gkab197
Abstract: Abstract In viruses and cells, DNA is closely packed and tightly curved thanks to polyvalent cations inducing an effective attraction between its negatively charged filaments. Our understanding of this effective attraction remains very incomplete, partly… read more here.

DOI: 10.1126/sciadv.aav1083
Abstract: Optical tweezers and single-molecule polarization imaging reveal structural features of overstretched DNA. DNA structural transitions facilitate genomic processes, mediate drug-DNA interactions, and inform the development of emerging DNA-based biotechnology such as programmable materials and DNA… read more here.
