Kemtec®. For building a scale model (1 cm = 1Å) of the double-stranded deoxyribonucleic acid molecule. Students learn the detailed chemical structure and sequence of polynucleotides and observe the basis for polarity within the phosphate-sugar backbone, features relevant to the genetic function of the molecule.

Kemtec®. For building a scale model (1 cm = 1Å) of the double stranded deoxyribonucleic acid molecule. Students learn the detailed chemical structure and sequence of polynucleotides and observe the basis for polarity within the phosphate-sugar backbone, features relevant to the genetic function of the molecule. Sixteen base pairs provide numerous coding triplet (codon) possibilities. The completed model, in the shape of a double helix about 55 cm H, demonstrates the spatial relationships in DNA revealed by Watson and Crick.

It is held together by a metal shaft on a wooden base. All molecular components are flexible plastic, white in color, with Pop-It Bead connections. With instructions.

Rated 3 out of 5 by from DNA Kit good price poor quality The kit was not advertised as coming with many tiny pieces (that would be of poor quality) that you needed to paint and put together. It was suggested as a classroom activity, yet there was only one small bottle per color of paint. The paint was brightly colored, which was good. All of the pieces in the kit required removal of stray pieces of plastic leftover from the molds. In the student instructions there are some misspellings.The plastic was soft and the parts did not fit together without filing down (with a nail file) each of the tiny pieces to make them fit into the model. It will be nice once done but I would never do this activity with a class.

Rated 5 out of 5 by from Awsome Very helpful in learning the structure of DNA, a little over priced but worth it
