| Hello everyone. I am a high school student and have a ridiculous assignment for grade 12 uni-prep biology. I have to construct a model of DNA. I find it very weird to have to do such an assignment considering the level of the course and it being a course considered preparation for university. I am no good with arts and crafts stuff and need A LOT of help as this is due tomorrow. I have no idea how to make/construct the actual double helix part. It has to be at least 30cm tall but I am having a lot of trouble understanding how to bend something to make a double helix. Can anyone please help me? It will be very much appreciated. Sorry if this is not the right forum for such a thing like this. |

| I don't have any trouble with the base-pairing or anything like that. The only part i'm having trouble with is deciding what to make the double helix out of. How do I make it? I tried using coat hanger but its way too hard to bend into shape. It needs to be a 3d model so how can I make a double helix? I'm just not understanding the double helix structure I guess so its kind of harder to make it into a model I guess. |

| The double helix is just like a spiral staircase or a rope ladder twisted into a spiral. Pipecleaner is just thin wire with some fuzzy coat on it. If you can find wire and yarn, and basically construct a mini ladder with wire as rigid sides and yarn as rungs (H-bonds) and the yarn knots on the wire representing the bases. You should be able to gently twist it into a spiral and the right scale/dimensions will allow for the wires' rigidity to support itself. You can glue it or weigh it down at the base so it will stand. |
