DNA Double Helix Structure - Scientific Illustration #1625478 (License: Personal Use)

This high-resolution illustration depicts the classic Watson-Crick DNA double helix, featuring two antiparallel black strands representing the sugar-phosphate backbone, connected by horizontal rungs of complementary base pairs-colored orange and cyan for visual distinction. The clean white background enhances clarity, making it ideal for educational diagrams, scientific publications, or digital learning modules. The structure accurately reflects the right-handed helical conformation and uniform spacing of base pairs.
