## Abstract For centuries, physicists and engineers have been battling image aberration in microscopes. With high resolution transmission electron microscopes they have minimised the flaws yet further – allowing the progress of research and technology to continue
## Abstract High‐resolution NMR studies of an α‐homo‐DNA:RNA duplex reveal the formation of a right‐handed parallel‐oriented helix. It differs significantly from a standard A‐ or B‐type helix by a small twist value (26.2°), which leads to a helical pitch of 13.7 base pairs per helical turn, a negat
## Abstract Published data indicate linear variation of the duplex winding of DNA with logarithm of the ionic strength. We show that this observation is a natural prediction of a current poly‐electrolyte theory if structural coupling between duplex rotation angle (rotation per base pair) and step h
