This is an example of a DNA molecule in CAD. DNA stands for deoxyribonucleic acid. It can be found in any living plant or animal, and it is one of the most important molecules in our bodies. DNA also holds our genes inside of it, and that is what makes everyone unique! It also makes important proteins such as keratin, which is found in our hair and nails. The specific atoms that DNA is made of are carbon, hydrogen, nitrogen, oxygen, and phosphorus. These elements make nucleotides, which are made of a sugar molecule, a phosphate group, and a nitrogen base. Only certain sets of nucleotides can fit together. When all of these pieces do fit together, the DNA’s shape forms a fantastic double helix.
