Wear A Chimp On Your Wrist
What To Do

bases in DNA Your bracelet will contain two strands of beads. The two strands will match up in the same way the bases in DNA, do: A always goes with T, and C always goes with G. So every time you put a bead on one strand, you must add its partner bead to the other strand.

The chart on the right will help you keep track. You can do both strands yourself, or you can string one side and have a friend string the other.

(We used green, pink, yellow, and purple beads. But you can use any four colors. And if beads aren't your style, try gumdrops.)

Base Pair Chart
1 Choose one DNA code from the chart on the What You'll Need page. Follow that pattern as you make your bracelet.

(The sample bracelet shown here represents part of a chimp's real DNA code.)

Choose one DNA code from the chart on the What You'll Need page.
2 Cut two pieces of string, each about 12 inches long. (Remember, your bracelet will contain two strands, just like real DNA.)
3 Tie at least one knot about two inches from one end of each string. You may need to tie more than one knot so that the beads don't slip off. Tie at least one knot about two inches from one end of each string.
4 Thread a bead onto String 1. Then thread the bead for the matching base onto String 2. For example, if you use a "C" on String 1, then you must put a "G" on String 2. Thread a bead onto String 1. Then thread the bead for the matching base onto String 2.
5 Keep threading beads until your bracelet is long enough to slip your hand through. (You do not have to use all the letters in the DNA code.) Keep threading beads until your bracelet is long enough to slip your hand through.
6 Tie a knot around the last bead of each string. Then tie the ends of the strings together to complete your bracelet.

Try It With A Twist
DNA is two strands twisted together in a double helix. Twist your two strands together so that the correct beads match up. If you want them to stay twisted, wrap a thread around the two strands.
