The difference between a Chromosome, DNA and a gene?

The difference between all of them is very simple Chromosomes are inside the nucleus when you look in a microscope and its an animal cell. DNA is the little section of the chromosome if you magnify part of the chromosome. A gene is a section of DNA from a chromosome that has the instructions to build the protein.

What does the materials each represent?

The black and red licorice represent parts of the sugar and phosphate backbone of the DNA. The toothpicks are used to represent the bonds in the DNA.

The marshmallows are the four bases which include

Pink: (C)Cytosine, Yellow (A)Adenine, Green: (G)Guanine, Orange: (T)Thymine

Did this experiment help you understand DNA?

Yes, it gave me a great visual representation of the pattern of A and T and the other combination of C and G. It also helped me understand what each part does
