| Build a DNA model! This kit contains everything you need to construct a double-helix model of DNA out of Styrofoam, chenille stems, and wire.
Included in this kit:
- 20 small Styrofoam balls (1 in.) for phosphate groups
- 20 large Styrofoam balls (1 1/2 in.) for deoxyribose sugars
- 10 long Styrofoam rods (2 1/2 in.) for adenine and guanine bases
- 10 short Styrofoam rods (2 in.) for thymine and cytosine bases
- 10 short chenille stems (3 in.) to connect bases and sugars
- Two extra-long chenille stems (45 in.) for sugar-phosphate “backbone”
- One reinforcement wire (14 1/2 in.)
- One display stand (4 in. x 5 in.)
- Complete instructions
The kit also comes with pop quiz, fundamental facts about DNA, and web links to sites about DNA, genetics, and biology.
