DNA Helix - Free Crochet Pattern by Nicki's Homemade Crafts

April 25th is International DNA Day!

As I have a BS in Biochemistry and Cell Biology from UCSD and work in research which is focused on sequencing and analyzing DNA and RNA to learn more about how to cure and prevent diseases, this day means a lot to me.

DNA is so important to understand, not just for people in science. But the reason we have so many different diseases in the world that we can treat now or even prevent is because of the understanding of DNA.

Before I geek you out too much, let me tell you have to make this pattern. But, in case you want to know more about science and what I do and how you can donate to research to cure and prevent diseases, please just contact me. I am happy to tell you more about it.

What can you do with this DNA crochet pattern? Well, you can use it to educated others or even make a bunch of them or one giant one for a school for educational purpose. Maybe you want to shrink it down and make it as earrings or a keychain or even a bracelet or necklace. So many possibilities.


You will need:

  • any type of yarn, depending on what you want to do with it (I used Caron Simply Soft in the color bone and Knit Picks Dishie in color blush)
  • a corresponding hook (I used a 5.0mm)
  • scissors
  • tapestry or yarn needle

Before you start it is important to understand, that you will need to make adjustments to be able to crochet the correct DNA chirality. DNA turns towards the right which means if you crochet right handed the DNA will turn towards the left and that would be wrong.

So unless you are left handed or can crochet left handed you will need to either learn to crochet left handed or crochet the below instructions backwards (like the crab stitch), so the DNA will turn the correct way.

  • make a chain in the length of your desire (for a DNA bracelet I used 23 chains)
  • starting from the second chain from the hook crochet 3 dc in each chain, until the last chain where you crochet 3 dc, ch 1, 1 sc, ch 1, 3 dc all in the same stitch
  • now you work your way backwards, in each chain crochet 3 dc again
  • sl st when you reached the end

If you feel the tension is too tight and it does not look right, try doing 2 dc’s instead of 3 dc’s. That might help 🙂

Now you can either fasten off and weave in the ends or attached it to something such as earrings, keychain or anything else.

It is a very easy pattern if you know how to either crochet left handed or know how to crochet backwards.

PLEASE SHARE THIS PATTERN on social media as SCIENCE IS IMPORTANT! WE NEED STEM in the kids schools!
many schools don’t have the finances to be able to have STEM classes! Let’s bring awareness by making these DNA Helixes and share them!
STEM stands for Science, Technology, Engineering and Math!
Thank you!
