The Double Helix -Glass Bead DNA model V2.0

Here is my second glass bead DNA double helix model. In this model I used wire instead of thread and I also added more space between the base pairs.

Here is a link to my first model.

Step 1 Materials:

-Five different colours of seed beads (I used glass beads).

• one colour makes up the sugar-phosphate backbone.
• four colours for the bases, pair up the colours so that they always appear together. (eg red-blue, green-yellow).

- ~50cm strand of jewelry wire (should be more than you need, but rather have too much than too little).

-Scissors for cutting the wire.

Cool, I've always wanted to crochet DNA.

I'v done some of this myself and I love them. Ive also made some molecule models out of beads. Yes, I'm a helpless geek!! But actually I have a problem in trying to keep the darn thing twisted. Any ideas?

[ChrysN]

It may be the type of wire that you are using that can cause it to become untwisted, maybe try something more rigid. The stuff I use seems to keep it's shape, unfortunately I don't remember where I got it and there is not much information about the type of wire it is on the label.

You are a life saver!! I just did this project with my 7th grade daughter for her science project. Everything was clear and the pictures were wonderful. Not to mention fun! Thank You and Have a Happy New Year

Thanks, Happy New Year!

I love this project! You provide simple steps and clear pictures and its very easy to follow! I literally just finished this and it took maybe half an hour? But I'm slow, haha! Mine looks nearly identical to yours (with the exception of different colored beads). I highly recommend this to any science lover! 5/5!

Thanks, I'm glad you liked it!

I've actually made 3 of them...2 12bp and turned into earrings and one 20bp into a pendant for a necklace. They're really amazing! Thanks again for posting this project!

Amazing, I am glad I checked instructables today!

That's so awesome :D I like both versions of it. One of these would make an awesome keychain...

[ChrysN]

Thanks, this one made with wire may be a bit more durable for a keychain.

Sweet! I love bio-nerd jewelery. Will have to give this a try. ;)
