Genes in a Bottle: Capture Your Unique Essence!
Once your students have extracted genomic DNA from
their cheek cells using the DNA extraction module
(catalog #166-2000EDU), the DNA strands can be
collected and transferred to a helix vial. The helix vial is
then fashioned into a necklace that can be worn with
pride, kept for posterity, or shared with a loved one!
Be the first on your block to wear DNA!

Learning opportunities for all levels of instruction.
This activity is designed for any classroom environment
and requires no specialized equipment or stains. For
middle school students, it’s a perfect introduction to the
exciting world of DNA science. For secondary and college
level instruction, lessons on DNA structure and function,
cell structure, and enzyme function can be introduced or
reinforced with this laboratory activity.
We welcome your comments and suggestions. Have fun!

Genes in a Bottle: Capture Your Unique Essence!
Instructions
1. Using a disposable plastic transfer pipet, carefully
transfer an appropriate portion of the DNA in alcohol
into the helix vial. You do not have to fill the entire vial
with alcohol. (Note that students can share plastic
transfer pipets for transferring their DNA into the helix
vial.)
2. Place the screw cap onto the top of the helix vial and
tighten.
3. Slip the cord through the screw cap and tie the cord.
Optional: To permanently seal your DNA necklace, add super glue to
the outside threads of the helix vial (do not allow super glue to contact
the alcohol solution or hazing may occur), and then tighten the cap.
Allow super glue to dry with cap tightened.
Congratulations, you’ve created your very own
DNA helix necklace!
