DNA Structure Explained | Molecular Biology Visual Guide #3545768 (License: Personal Use)

This graphic depicts the classic Watson-Crick model of DNA, featuring two antiparallel strands twisted into a right-handed helix. The gray ribbons represent the sugar-phosphate backbone, while the black horizontal bars symbolize nitrogenous base pairs (adenine-thymine and guanine-cytosine). The clean, minimalist design emphasizes structural clarity over biochemical detail, making it ideal for educational contexts.

Commonly used in biology textbooks, online learning modules, and science outreach materials to introduce nucleic acid structure; targets users seeking foundational knowledge of molecular genetics or preparing for exams.
