2024年10月7日 · The double helix of DNA is characterized by two distinct grooves that spiral along its length: the major and minor grooves. These grooves arise due to the asymmetrical positioning of the sugar-phosphate backbones, …
Nucleic acid double helix - Wikipedia
In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure. The structure was discovered by Maurice Wilkins, Rosalind Franklin, her student
