Paper for Cutouts:
4 bases: A,T,G,C
Start by cutting out shapes you will be needing: enough to make 2 complimentary strands of DNA, each strand having 6 nucleotides.
Each nucleotide has a phosphate along the backbone, a sugar molecule, and a base
Continue making a strand of DNA, making sure all the sugar molecules point the same direction
When you have 8 nucleotides on one strand, make the complimentary strand. Follow base pairing rules and make sure the opposite strand has the sugars pointing in the opposite direction
Grading: Must have 6 complete nucleotides on each strand. Strands must compliment (follow base pair rules). Strands run in opposite directions. Must use all 4 bases. Strands must be orderly and clean in appearance.
