DNA Double Helix Structure - Molecular Visualization & Scientific Explanation #1688785 (License: Personal Use)

This high-resolution molecular visualization depicts the iconic right-handed B-form DNA double helix, with complementary base pairs (adenine-thymine in red/blue, guanine-cytosine in green/blue) connected by hydrogen bonds. The sugar-phosphate backbone is rendered in orange and red, while individual atoms are color-coded per standard CPK convention. The model highlights structural regularity, helical pitch (~3.4 nm per turn), and major/minor grooves critical for protein binding.

Used in biology education, genetics textbooks, scientific presentations, and biomedical websites to explain DNA architecture, replication, transcription, and gene regulation; targets students, researchers, and science communicators seeking visual reinforcement of molecular concepts.
