DNA Jewelry - Instructions

Instructions

1. String the following onto your wire: phosphate – sugar – base – correct number of seed beads (2 for A-T, 3 for C-G) – matching base – sugar – phosphate.
   
2. Onto one end, add: a base – correct number of seed beads (2 for A-T, 3 for C-G) – matching base. Do not push these beads down to meet the others.
   
3. Feed the free end through the beads you just added.

4. Pull the wire ends tight to form a loop. Then add to both free ends: sugar – phosphate. These may be pushed down to meet the others.
   
5. Repeat steps 2-4 until you have added as many rungs to your DNA ladder as you want.
6. To make the very last rung on your DNA and to tie it off, add one base to a free end and add its matching base to the other free end. These may be pushed down to meet the others.
   
7. Onto one end, add the correct number of seed beads (2 for A-T, 3 for C-G). Do not push these beads down to meet the others.
   
8. Feed the free end through the beads you just added.
   
9. Pull the wire ends tight to form a loop. If you wish to add an earring hook, loop, key ring, Christmas ornament wire, or other doo dad, add it to one free end.
   
10. Twist the wire ends together tightly. Cut the wire off 3-4 mm from the base of the twist.
11. Finally, add a slight counter-clockwise twist to the entire DNA molecule to form a double helix. You have now made lovely DNA jewelry!
