Hey guys,I would love if you could give me some ideas for how to make a DNA model.It could be 3-d or 2-d.I wanted to do something unique other than toothpicks and marshmellows.It could be made out of ANY materials and should look like the real thing.I really need an A on this project,so try to help me out.
Thanks in advance

I helped my oldest daughter in this exact same assignment. We used wire and beads. Make a fine wire ladder, string on a few beads, say 4 on each wire, then put a cross wire on with say 6 beads, then 4 more on each leg of the ladder and another cross member with 6 beads. Continue until it is long enough to satisfy you. Then twist a spiral into the whole thing. We used several colors of beads and put them on in a random sequence.
She got an A for it. If that means anything.
Good luck, hope this helps.

DNA is double stranded, and is a cells permanent copy of it's entire genetic information.
Watson and Crick (who worked out the structure of DNA in 1957)used 2d images of the 4 bases on stiff paper and connected them with small metal sticks. You could try toothpicks.

Depends where you live.
Lets assume you are in the USA. Do you have tiny tomatoes out there. I have a load in our garden...(sorry)
What about snails or seeds.
Things such as seed pods, or tree seeds, such as acorns, or fruit pips.
You need to think laterally.
What about one of those toy springs for a base, and you could build it from there.
It makes you even more in awe of nature, doesn't it?
Its a shame you dont have a spotlight store in the USA.
(Craft shop). I suppose you may have craft shops. Go for a look, it may inspire you.

DNA is a double helix. for the strands u can use two thick wires .wind them around each other and when u get the skeleton fit in thermocol balls with alpins for the sugar bases and nucleotides.different colors of balls can be used to represent different bases.try this out. its very cheap and looks very attractive. if u even wanna show the bese(adenine ,guanine etc) cut out alphabets ATGC on colored paper and fit them in between the alpins at the centre of the helix .itll become more clearer.
it should be connected like this:

How about pushing coloured sticks through a clear tube (like a 2l cola bottle? You could use tape or paint on the to represent the base pairs (remembering how they pair up!) and tape or paint on the outside of the bottle to show the double helix.

I can't understand how some people still don't understand the concept. It has been explained time and time again, and genetic sciences have helped humans a lot.

use clay and toothpicks
