The instrument D19 at the Institut Laue-Langevin, Grenoble, has been used to undertake neutron fibre diffraction studies of the location of water around the D form of the DNA double helix. These studies clearly show the distribution of water in the s

The development of neutron high angle fiber diffraction to investigate the location of water around the deoxyribonucleic acid (DNA) double-helix is described. The power of the technique is illustrated by its application to the D and A conformations o

A high angle neutron fibre diffraction study of the distribution of water around the A-form of DNA has been performed using the diffractometer D19 at the Institut Laue-Langevin, Grenoble. These experiments have exploited the ability to replace H2O su

Interactions with water are crucial to the conformation assumed by the DNA double helix. The location of water around the D conformation has been investigated in a neutron fibre diffraction study which shows that water is ordered in the minor groove

The synthetic polynucleotide poly[d(AT)].poly[d(AT)] is of interest in studies of the relationship between nucleic acid structure and function. In particular, A + T-rich regions in DNA double helices have been invoked as centres for controlling the t

An intriguing topological problem posed by the double-helical Watson-Crick model of DNA is that of unwinding the intertwined strands during replication. Several workers have recently proposed novel side-by-side (SBS) structures for DNA. In all these
