DNA Molecular Anatomy Model Paramecium model base ten blocks are imperativeThis 22 layer 11 layer model (two complete turns of the double helix) is designed for self assembly, with the double helix structure becoming self evident as the model is constructed. Components include color coded bases (G, C, A and T), deoxyribose and phosphate groups. Structural details include the major groove minor groove of the double helix, and correct representation of the hydrogen bonds between the bases, G+C and A+T. The model may be
