DNA Structure Explained - Double Helix Diagram for Science Education #117271 (License: Personal Use)

This stylized illustration depicts the classic Watson-Crick model of DNA, with two antiparallel strands forming a right-handed helix. Colored bars represent the four nitrogenous bases-adenine (red), thymine (green), guanine (blue), and cytosine (yellow)-paired according to standard rules. The backbone is rendered in yellow and green to emphasize sugar-phosphate chains.

Commonly used in educational websites, biology textbooks, and science outreach materials to introduce molecular genetics. Matches user intent for visual learning, classroom instruction, or quick reference on DNA structure.
