DNA origami: how to fold a double helix

Показать описание

This hands-on activity allows you to create your own paper model of a DNA double helix. DNA has a ‘double helix’ structure. Much like a spiral staircase, it has two single strands that join and twist together. The ‘steps’ of the staircase are made up of the four bases of DNA (adenine, cytosine, guanine and thymine). These bind together in complementary pairs (A with T, C with G).

This totally saved me for Biology homework due tomorrow (lost instruction sheet!)

I legit got triggered with the twisting part that I squished it completely together and threw it across the room... guess whose getting an F

the video: twist the model, "BE BRAVE".
me: twist it and it become trash.

who else had trouble with the twisting part?

If you need help with the twisting part:
1. make sure your diagonal creases are made well and are not overlapping the white part as he said in the video.
2.Make the diagonal creases more hard (fingernail) and lift the white tabs up more.
3. Twist first, then push together, try not to disturb the diagonal creases while doing this.
4. Try it again.
5. If this doesn't work, you can either restart, or do this:
6. Hold the paper horizontally. So its longer upwards than sideways, if that makes sense. Then take the first diagonal crease from the top in your fingers. Put the second diagonal crease in the same fingers, and keep moving down. this should make it all fall into place. Once you get to the middle, keep your hand there and to your best to do the same to the bottom portion. It'll be kinda hard, you'll have to maneuver around the white tabs which can be annoying. Stick with it.
7. If it still doesn't work then your creases are fucked.

Hope this helped!

Thanks a bunch, helped me with my project a shit ton!

Like this so people can see! :)

The dislikes are from the people who messed up with the twisting part.

If you need help with the twisting part and you're just barely getting the shape, I find the best way to finish the entire twist is to fold the remaining piece of the paper in the pattern that is given.
So basically, fold diagonal then straight, repeating.

This was life saver. Thank you! For those who are struggling with the twisting part, just take the print of the template on a thicker paper, where one side of the paper is glossy (just as shown in the video), it gets really easier with it.

if twisting it doesnt work (most cases it wont), just try folding it bit by bit. if you made sure all your creases are really good, it will eventually work.

seriously...., follow the instructions and it virtually twists itself! Hugely satisfying, first time 'right'.

Thanks for wasting loads of my time by creating this video so my teacher can set it for homework :) BTW you have a lovely voice ;)

The end confuses me I have no idea how to get it to twist like that

Thank you! I have been racking my brain all week on how I would make my son's double helix and this is the easiest demonstration I have found!
