DNA Structure Illustration - Double Helix Model for Genetics Education #179390 (License: Personal Use)

This image depicts the iconic Watson-Crick model of DNA, featuring two antiparallel strands twisted into a right-handed helix, with colored nucleobases (adenine, thymine, guanine, cytosine) forming hydrogen-bonded pairs. The black backbone represents sugar-phosphate chains, while the gradient background provides visual contrast and modern aesthetic appeal. Widely used in textbooks, presentations, and digital learning modules to explain molecular genetics fundamentals.

Used in educational websites, university course pages, scientific articles, and health literacy resources to illustrate genetic structure; matches user intent for learning or teaching basic molecular biology concepts.
