DNA Structure Explained: Double Helix with Base Pairing Labels #1422348 (License: Personal Use)

This high-resolution illustration depicts the iconic right-handed double helix structure of DNA, with the sugar-phosphate backbone forming the outer rails and nitrogenous bases pairing inward. Adenine (red) binds specifically with thymine (green), while cytosine (blue) pairs with guanine (black), demonstrating Watson-Crick complementarity. Each component is clearly labeled for educational clarity.

Used in biology textbooks, online learning modules, and science websites to teach molecular genetics; targets students, teachers, and curious learners seeking foundational knowledge of DNA architecture and replication.
