Comparative review on left-handed Z-DNA

Being polymorphic, deoxyribonucleic acid is worthy of raise a variety of structure like right-handed B to left-handed Z conformation. In left-handed contour of DNA consecutive nucleotides substitute between syn-arrangement and anti-arrangement, through the chain. 2D gel electrophoresis comprising d(PCpG)n of topo isomers of a plasmid inserts d(pCpG)n, in this 'n' ranges among 8 to 21, indicate the change of B-Z DNA. The high denseness of salt is...
