DNA Structure Diagram - Visual Representation of Genetic Code #3659320 (License: Personal Use)

This hand-drawn-style illustration shows the classic right-handed double helix conformation of DNA, with sugar-phosphate backbones in red and blue, and paired nitrogenous bases (adenine-thymine, guanine-cytosine) rendered in distinct colors. The image emphasizes the antiparallel orientation and hydrogen-bonded rungs of the genetic ladder, ideal for teaching molecular biology fundamentals. Its transparent background allows seamless integration into digital educational materials.

Used in biology textbooks, science websites, classroom presentations, and genetics education platforms to visually explain DNA structure, replication, and heredity. Matches user intent for visual learning, academic reference, or科普 content creation.
