The invention is a dynamic model of the DNA molecule. The invention includes a multiplicity of physical representations of the four nucleotides. Each physical representation is comprised of T-shaped members having an elongate body attached to a flexible planar member. The invention also includes a first joint, located at an end of the elongate bodies which physically represent the Adenine base and the Thymine base, for attaching the Adenine base to the Thymine base, wherein the joint is rotatable. The invention further includes a second joint, located at an end of the elongate bodies which physically represent the Guanine base and the Cytosine base, for attaching the Guanine base to the Cytosine base, wherein the joint is rotatable. Lastly, the invention includes a connections between the nucleotides and the flexible planar member. The flexible planar member physically represents the sugar-phosphate structure of the DNA molecule. Preferably the elongate bodies are made-up of a rigid material, and the flexible planar members are made-up of vinyl. It is also preferred that the joints and connections are easily engaged and disengaged.
