DNA Double Helix Structure - Scientific Visualization #1422551 (License: Personal Use)

This high-resolution 3D model visualizes the canonical B-form DNA double helix, with antiparallel strands wound around a central axis. Each nucleotide is distinctly colored: purines (adenine in red, guanine in yellow) and pyrimidines (thymine in green, cytosine in blue), connected via hydrogen bonds, while the sugar-phosphate backbone is shown in alternating red and green ribbons. The structure emphasizes key features like major and minor grooves, helical pitch, and base stacking interactions.

Used in biology education, scientific publications, museum exhibits, and medical websites to explain genetic coding, replication, and molecular biology fundamentals; targets students, researchers, and curious learners seeking visual understanding of DNA architecture.
