WebCarbohydrates are biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom ( \text C C) to one water molecule ( \text H_2\text O H2O ). This composition gives carbohydrates their name: they are made up of carbon ( carbo -) plus water (- hydrate ). Carbohydrate chains come in different lengths, and ... WebDNA molecules arrange themselves in a model called the DNA double helix. It’s a 3-D structure that is stored in the nucleus of all cells. Remember that the phosphate and sugar molecules are the backbones of the ladder. …
