Genes are segments of DNA and DNA strands form chromosomes.
The licorice represents the sugar/phosphate backbone, the marshmallows represent the bases. A green marshmallow represents Guanine, pink represents Cytosine, yellow represents Adenine, and orange represents Thyme.
This activity helped me understand that if a certain part of the DNA is missing, that causes a mutation. It also helped me understand how the backbone, bases, and bonds work to create DNA.
