DNA Model
• DNA can be compared to a ladder that is twisted into a continuous spiral shape known as a double helix
• Each step contains pairs of chemicals
• Adenine and Thymine pair together • Guanine and Cytosine pair together

Gene
• A gene is thought to be a interrupted segment of DNA that contains coded instructions for specific traits.
• Genes come in pairs and each possible version of a gene is called a allele
