DNA Double Helix Structure - Visual Guide to Genetic Code #239370 (License: Personal Use)

This high-resolution 3D visualization depicts the classic Watson-Crick DNA double helix, with green and blue strands representing the sugar-phosphate backbones and red, orange, purple, and cyan spheres denoting the four nucleobases (A, T, G, C). Hydrogen bonds between complementary base pairs stabilize the helical structure, while the right-handed twist reflects natural B-DNA conformation. The image highlights both structural symmetry and biochemical specificity essential for replication and transcription.

Used in educational biology resources, genetics textbooks, university lectures, and science outreach websites to explain molecular biology fundamentals; targets students, educators, and curious learners seeking visual understanding of DNA architecture.
