DNA is generally assumed as a right-handed double helix and Z-DNA is aspecial kind of left-handed DNA infrequently found in nature. However, thefinding of a zero linking number topoisomer supports a hypothesis that the twostrands of DNA are winding ambidextrously, rather than plectonemically...

Imagine that the double helix is a spiral staircase, and you’re walkingdownthe staircase. If you’re turning to the right as you descend, the DNA structure is right-handed; if turning to the left, it’s left-handed. In the image shown earlier, the DNA molecule on the right is a ri...
Z DNA and loop structures by immunoelectronmicroscopy of supercoiled pRW751, a plasmid containing left-handed helices. Single and multiple loops were seen when the plasmid pRW751 was allowed to react with anti-Z-DNA or with a Z-specific cross-linking agent. Loop formation w... H Castleman,...
I must protest against the knowing groans expended every time a scientist is personally affronted by the image of a left-handed DNA helix (Nature467, 401; 2010). I would remind the groaners that DNA handedness depends on its molecular sequence — witness a seminal paper you published more ...
It contains multiple domains of half-turn-long, standard B-DNA duplexes. While each helical domain is right-handed and its two component strands are antiparallel, the global architecture is left-handed and the two component DNA strands are oriented parallel to each other.关键词:...
