DNA Double Helix Structure - Visual Guide to Genetic Code #85568 (License: Personal Use)

This illustration depicts the classic Watson-Crick model of DNA as a right-handed double helix, with sugar-phosphate backbones in purple and paired nitrogenous bases (A-T, G-C) forming the rungs. The clean, high-contrast design emphasizes structural symmetry and molecular organization, making it ideal for educational use. Subtle shading adds depth while preserving scientific accuracy for introductory biology contexts.

Used on educational science websites, biology textbooks, university course pages, and health/medical explainer articles to visually introduce DNA structure; matches user intent for learning basic genetics or preparing teaching materials.
