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.) |

 |
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.) |
 |
 |
 |
Cut two pieces of string, each about 12 inches long. (Remember, your
bracelet will contain two strands, just like real DNA.) |
 |
 |
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. |
 |
 |
 |
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. |
 |
 |
 |
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.) |
 |
 |
 |
Tie a knot around the last bead of each string. Then tie the ends of
the strings together to complete your bracelet. |

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. |
