DNA Structure Explained: Double Helix, Base Pairs, and Hydrogen Bonds #1422354 (License: Personal Use)

This diagram depicts the iconic double helix structure of DNA, highlighting complementary base pairing-adenine (A) with thymine (T), and cytosine (C) with guanine (G)-held together by hydrogen bonds. The sugar-phosphate backbones run antiparallel (5′ to 3′), and each nucleotide is color-coded for easy identification. Key structural features like base stacking and bond geometry are emphasized for clarity in teaching genetics and biochemistry.

Used in educational websites, biology textbooks, and science outreach pages to explain foundational molecular biology concepts; targets students, educators, and curious learners seeking visual understanding of DNA architecture.
