DNA Structure Explained: Double Helix and Base Pairing #3407538 (License: Personal Use)

This vector illustration depicts the classic Watson-Crick model of DNA as a right-handed double helix, with two antiparallel strands forming a twisted ladder. The rungs represent hydrogen-bonded nucleotide base pairs-adenine with thymine (two bonds) and guanine with cytosine (three bonds)-highlighted in contrasting colors for clarity. The clean, modern design emphasizes structural accuracy while remaining accessible for educational use.

Commonly used on biology education websites, textbook digital editions, and science outreach pages to explain genetic fundamentals; matches user intent for visual learning about molecular genetics or preparing classroom materials.
