| abstract |
A model for representing chemical structures such as deoxyribonucleic acid and the like, and including a combination of individual units with projections and apertures formed as part of the units whereby the apertures are adapted to receive and removably retain the projections in a manner permitting relative movement between adjacent units within the model. One alternative embodiment includes the use of permanent magnets formed as a part of the units for connecting the units together in lieu of the projections and apertures. Means are provided for supporting the units in a desired shape. |
