DNA Structure Explained: Double Helix and Base Pairing #1422537 (License: Personal Use)

This vivid 3D illustration depicts the iconic right-handed double helix structure of DNA, with sugar-phosphate backbones in orange and blue, and hydrogen-bonded base pairs in yellow, green, cyan, and red. Each nucleotide pair is clearly labeled-adenine (A) pairs with thymine (T), and cytosine (C) with guanine (G)-highlighting the specificity of Watson-Crick base pairing essential for replication and transcription. The clean, high-contrast design makes it ideal for teaching core genetics concepts.

Used in educational websites, biology textbooks, science outreach pages, and classroom presentations to explain DNA architecture and genetic coding; matches user intent for learning or teaching molecular biology basics.
