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.
