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?

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.

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!

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!
