DNA Structure Illustration | Genetics Education Resource #3401407 (License: Personal Use)

This digital illustration depicts the classic Watson-Crick model of DNA as a right-handed double helix, with sugar-phosphate backbones in gradient purple and magenta, and horizontal base pairs shown as alternating colored rungs. The clean vector-style design emphasizes structural clarity over biochemical realism, making it suitable for teaching materials and scientific presentations. The contrasting dark teal background enhances visual focus on the helical geometry.

Commonly used in biology textbooks, online courses, science museum exhibits, and health/education websites to introduce or reinforce concepts of genetic coding, replication, and molecular structure; targets students, educators, and general audiences seeking foundational knowledge.
