Nucleosome positioning is critical for gene expression and most DNA-related processes.
Here we review the dominant patterns of nucleosome positioning that have been observed …

Interactions between aromatic molecules represent an important class of intermolecular
force in chemistry, biology, and materials science. They control a range of molecular …

The rotational positioning of DNA about the histone octamer appears to be determined by
certain sequence-dependent modulations of DNA structure. To establish the detailed nature …

Abstract Poly (dA)· poly (dT) has unusual properties in that it cannot associate into
nucleosomes and short, phased runs of it cause DNA bending. The crystal structure of a B …

The high degree of DNA protection provides the specialized cells of Bacillus species
resistance to damaging treatments including dessication, heat and radiation and a variety of …

Many yeast promoters contain homopolymeric dA: dT sequences that affect nucleosome
formation in vitro and are required for wild‐type levels of transcription in vivo. Here, we show …

In both DNA and RNA, stretches of guanine bases can form stable four-stranded helices in
the presence of sodium or potassium ions. Sequences with a propensity to form guanine …

Mixed sequence DNA can exist in two right-handed and one left-handed double helical
conformations—A, B and Z1–3. Under conditions of high water activity the B conformation …

We report direct measurements of the intrinsic electrical characteristics of polynucleotides
using a conducting-probe atomic-force microscope under vacuum. Poly (dA)⋅ poly (dT) self …

Bovine pancreatic deoxyribonuclease I (DNase I), an endonuclease that degrades double-
stranded DNA in a nonspecific but sequence-dependent manner1–4, has been used as a …
