Method #2: dna model using pipe cleaners. pipe cleaners or chenille craft sticks are a good alternative to licorice for making the double helix ladder. although they are technically wire, the fuzzy coating helps hold “base pairs” in place. plus, scissors easily snip them apart. pipecleaners.

Twisted pipe cleaner model: create a simple dna double helix using colorful pipe cleaners. lego dna model: construct a basic dna structure using lego bricks. straw dna model: assemble a dna model with drinking straws and adhesive materials. paper dna model: craft a paper dna helix with colored strips and glue. Check out some of the exciting facts about dna given below: it is found in all eukaryotic and prokaryotic cells. there are three types of dna; a dna, b dna and z dna. it is responsible for storing genetic information in organisms. the length of the dna helix is 3.4 nm, and the distance between two base pairs is 0.34 nm. 2. take 24 of the balls and paint 12 green and leave 12 white. these green and white balls will make up the strands that run along the outside of your dna model, or the sugar and phosphate of your double helix. to paint half of the balls green, use a paintbrush to apply a thin layer of green, water based paint. Dna looks like a twisted rope ladder. in your model, you will use twizzlers for the "backbone" sides of the ladder and then add the candy "pair" rungs. to assemble your dna model, lay two twizzlers parallel to one another with about 8 cm of space in between. you will link the pairs of code chemicals to your dna backbones by attaching each pair.

Students will begin this project by choosing the dna sequence they'd like to model (a simple option is t t a a g a t t t g g t). 2. next they will need to assign a marshmallow color to each dna. Step 1. make your base pairs. start your candy dna model by sorting the 4 colors of candy into separate bowls. then you want to assign each one to a specific nucleotide. these 4 nucleotides along with the sugars and phosphates make up your double helix candy dna model. adenine.
