what should i use for my biology project?

Question

i have to make a DNA molecule out of household products. any suggestions? it's due in two days.

Answer 1

coloured mini marshmellows and tooth picks would work. you can even use a certain colour marshmellow for each type of nucleic acid.

I have seen a really cool bead project that is geared for teaching DNA structure

http://www.ology.amnh.org/genetics/stufftodo/bracelet_do.html
is good for younger kids

http://www.fresno.k12.ca.us/schools/S090/_atkinsgatebio/beadproject/GenJewel
This is a good site, but sometimes their server goes down. It has very explicit instructions on how to make aDNA model out of beads and then turn them into earrings. A Bio teacher wrote this.

Another thought would be to use those magnetix toys - sticks and round magnets are the main pieces of this kind of toy. If you have it around or a friend who will let you use theirs.

Hope some of this helps

Answer 2

You can do it on a hard paper, have a paper cut it in pieces (hexagonal may be) write about base pairs sugar phosphate backbone on each piece and join these pieces 3' to 5' there will be a chain of these molecules you can insert it in a hard (about 3 mm thick) wire which is having a bottom support. Also you can show bonding on this two anti parallel strands of DNA.

Answer 3

Marshmallows and toothpicks are always a good idea, but if you want to get really creative, use bread rolls, or bottle caps, or popsicle sticks...
The possibilities are endless.

Answer 4

You could use toothpicks and different colored gum drops. The different colors will represent the different DNA.

Answer 5

Marshmallows and toothpicks and, if you get really creative, licorice.

Answer 6

well i did do this one before
we used beads, thread
