The various nearest neighbor stacking interaction energies of stacked base pairs in the DNA
double helix are calculated for both A-and B-type conformations using an ab initio molecular …

The structure of d (CGCGCG) crystallized in the presence of magnesium and sodium ions
alone is compared to that of the spermine form of the molecule. The very high resolution …

This review summarizes results concerning molecular interactions of nucleic acid bases as
revealed by advanced ab initio quantum chemical (QM) calculations published in last few …

We review the effect of sequence on the structure of left‐handed Z‐DNA in single crystals.
The various substituent groups that define a nucleotide base as guanine, cytosine, thymine …

The DNA oligomer d (CGCGTG) crystallizes as a Z‐DNA double helix containing two
guanine‐thymine base pair mismatches of the wobble type. The crystal diffracts to 1 A …

Base stacking is a major interaction shaping up and stabilizing nucleic acids. During the last
decades, base stacking has been extensively studied by experimental and theoretical …

Sequence-dependent configuration changes and condensation of double-stranded poly (dG-
dC)·(dG-dC)(GC-DNA) and ds poly (dA-dT)·(dA-dT)(AT-DNA) were observed by atomic force …

The polymorphic nature of double helical DNA, as expounded by Stanley Bram in the 1970s
(1), is now well established (2-4). The interconversions between alternative conformations …

Revised Manuscript Received February 20, 1992 abstract: A method has been developedto
solve structures of DNA oligomers in solution from the experimental NOE data. The method …

Ab initio quantum chemical calculations with inclusion of electron correlation effects
