DNA Structure Explained - Double Helix Diagram for Science Education #85567 (License: Personal Use)

This illustration depicts the classic Watson-Crick model of DNA, featuring two antiparallel strands twisted into a right-handed helix. The purple ribbons represent the sugar-phosphate backbones, while the colored rungs (red, orange, green, blue) symbolize complementary base pairs-adenine-thymine and guanine-cytosine. Designed for clarity, it balances accuracy with accessibility for educational use.

Commonly used in biology textbooks, online learning modules, medical infographics, and science outreach materials to explain genetic structure; matches user intent for visual learning, academic reference, or科普 content creation.
