How To Make A 3d Model Of Dna. Making your own dna model is a fun science project that you can do with all kinds of easy to find materials. Cut a 24 inch long piece of the lighter gauge wire.
Two colors to be the phosphate and sugar on the sides of the dna i almost always pick black and white but it is up to you four colors in two groupings to be the bases. To make a dna model using supplies you probably already have take 4 pipe cleaners and cut 2 of them into 2 inch strips. To make a 3d model we need to make two strands sugar and phosphate and then pairs of nitrogenous bases adenine and thymine and cytosine and guanine.
Remember dna always twists to the right.
Let the balls dry. Using either pipe cleaners and tape or styrofoam balls and toothpicks you can build a 3 dimensional model that has all the components of a double helix including the sugar deoxyribose and phosphate backbone and the nitrogenous bases cytosine thymine guanine and adenine. Cut an 18 inch long piece of the heavier gauge wire. To make a dna model using supplies you probably already have take 4 pipe cleaners and cut 2 of them into 2 inch strips.
