This vibrant 3D illustration depicts the classic Watson-Crick model of DNA, featuring two antiparallel strands (green and red) forming a right-handed helix, with complementary base pairs (blue vertical bars) connecting them. The clean, schematic design emphasizes structural clarity over biochemical realism, making it ideal for educational and scientific communication. Lighting and shading enhance depth, reinforcing the molecule’s three-dimensional nature against a black background.
