DNA model China

This double helix DNA model is pre-assembled and is a very impressive display and learning tool. The phosphate-deoxyribose backbone and four bases are represented by custom plastic molds that show the shape of the molecules in proportion and illustrate the bonding between them. The handedness of the backbone chain and the relative size of the main groove and the secondary groove in the relaxed molecule are correctly described. The model is vertically mounted on a circular support and can be rotated to view all components. Phosphate and deoxyribose are accurately delineated and can be removed and separated for further examination. And each base pair. 3277 Adam Jee Rd, Saddar, Rawalpindi, Punjab 46000, Rwalpindi, Rawalpindi, Punjab, Pakistan
