DNA’s iconic double helix has long been the symbol of life’s blueprint. However, the human genome conceals far more complexity. Among these mysteries are i-motifs, unusual knot-like DNA ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

They chose negatively supercoiled DNA -- an underwound and twisted form of the double helix -- because it better mimics the natural state of bacterial DNA than the linear DNA often used in ...

National DNA Day celebrates the “discovery of the DNA double helix structure,” which is used in genealogy to trace your family ancestry. For 2023, the holiday marks 70 years since the ...

Franklin, working mostly alone, found that her x-ray diffractions showed that the "wet" form of DNA (in the higher humidity) had all the characteristics of a helix. She suspected that all DNA was ...
