Biological DNA double helix 3D model with organic granular textured surface, golden translucent texture with natural gradient light and shadow effect against pure black background.

The helical chain structure is divided into independent segments, supporting rotation, stretching and unwinding animation production. The bump texture simulates the stacked structure of biological base pairs, with realistic subsurface scattering material effect.

Perfect for genetic science teaching videos, biomedical presentation scenes, gene research animations, biological microscopic scenes, science poster rendering and medical technology visual design.

Compatible with Blender
