1. Describe the difference between chromosomes, DNA and genes.

A chromosome is a structure that is made up of a chemical known as deoxyribonucleic acid, or DNA as well as protein. Chromosomes are found in the nucleus of cells,they contain many genes. A gene is a molecular unit of genetics. the difference between the three is that genes are intangible, they are a trait that you pass down for generations. Chromosomes are inside the nucleus and DNA is the physical thing double helix.

2. What each part represents. 

Black/red liquorice: each piece of the liquorice represents half of the double helix. The sugar/ phosphate back bone

Marshmallows: the marshmallows represent the bases between the double helix’s

Pink: cytosine

Yellow: adenine

Green: guanine

Orange: thymine

Toothpicks: the toothpicks represent the bonds between the bases and the helix’s

3. Did this activity help you understand DNA explain:

Personally I did not do this lab because I was away but if I was to do this lab I think it would help me understand the parts of DNA and how everything is connected to everything and how it all works
