DNA Pipe Cleaner Model
Activity Summary
Deoxyribonucleic Acid (DNA) contains genetic information in humans and many other organisms. DNA is made up of phosphate, sugar and one of 4 bases. The bases are adenine (A), thymine (T), cytosine (C), and guanine (G). In this activity students use colored pipe-cleaners and beads in a hands-on activity to emphasize base pairing (A-T) and (G-C) as well as the double helix shape of DNA.
