The Double Helix Structure in Molecular Biology defines the canonical three-dimensional conformation of deoxyribonucleic acid, characterized by a right-handed sugar-phosphate backbone enclosing a central stack of nucleotide bases. This structural paradigm relies on antiparallel strand orientation and specific hydrogen-bonding geometries between complementary nitrogenous bases, establishing a universal physical model for genetic information storage. It represents a fundamental axiom within structural biology and biophysics, governing the thermodynamic stability and informational capacity of nucleic acid polymers.
Prerequisite chain context: requires Nitrogenous Bases as Alphabet in DNA.
