Scientists have long known that handedness is partly shaped by genes. But it wasn’t until 2019 that they identified differences in parts of the DNA of left- and right-handers. The study, which also analyzed brain scans of 9,000 British subjects, found that in lefties, the parts of the...
It can be challenging, at first glance, to tell whether an image of DNA is left-handed or right-handed. Various helpful hints are available; however, the one that I’ve found easiest to remember is described in ablog postby Professor Emeritus Larry Moran at the University of Toronto: Imag...

Cytosine methylation has energetic and structural influences on left-handed Z-DNA formation in supercoiled plasmids. The restriction and modification enzymes from Haemophilus haemolyticus (HhaI and M · HhaI) provide a system to locate and analyze small segments of Z-DNA in large supercoiled plasmids...
(Nature467, 401; 2010). I would remind the groaners that DNA handedness depends on its molecular sequence — witness a seminal paper you published more than 30 years ago: 'Molecular structure of a left-handed double-helical DNA fragment at atomic resolution' (A. H.-J. Wanget al.Nature...

Molecular dynamics simulations were carried out for a right-handed and left-handed DNA heteropolymeric fragment, in which four different types of nucleotides constituted the sequence. The average structures obtained from the simulation converged to within 1.4 rms fluctuation for the left-handed and for...
The interaction of sanguinarine and ethidium with right-handed (B-form), left-handed (Z-form) and left-handed protonated (designated as H~L-form) structures of poly (dG-dC) centre dot poly(dG-dC) and poly(dG-me~5dC) centre dot poly(dG-me~5dC) was investigated by measuring the circ...
