DNA Structure Diagram - Base Pairs and Backbone Explained #1422350 (License: Personal Use)

This scientifically accurate illustration depicts the iconic double helix structure of DNA, with colored rods representing the four nitrogenous bases: adenine (green), thymine (yellow), guanine (red), and cytosine (orange). The sugar-phosphate backbone runs along the outer edges, while hydrogen-bonded base pairs form the internal rungs. Labels clearly identify key components to aid learning in biology and genetics education.

Used in educational websites, textbooks, and science outreach materials to explain molecular biology fundamentals; targets students, educators, and curious learners seeking visual reinforcement of DNA structure concepts.
