Nucleic acids are the molecules that carry the genetic information that is passed down from parent to child. However, nucleic acids are special since they can also combine with proteins to become the machines -- called ribosomes -- that turn genetic instructions in nucleic acids into other protein machines. Nucleic acids are linked together into a chain. DNA is made of two chains that connect like a rope ladder.
Nucleic Acids. Your cells contain two types of nucleic acids, ribonucleic acid and deoxyribonucleic acid, or RNA and DNA, respectively. They differ from the other macronutrients in that they are not a source of calories in your diet, and their role is strictly to direct the synthesis of new protein molecules.roteins. The building blocks that make up proteins are called amino acids. Proteins consist of 20 different amino acids, mixed and matched to create a vast array of larger molecules that support every process in your body.
