Nucleic acid is the basis of life. There are 2 types, ribose nucleic acid (RNA) and deoxyribose nucleic acid (DNA). DNA, the material found in the chromosomes within the nuclei of the cells of most living organisms, bears the genetic code that determines all of the characteristics of a living organism. Information from the DNA of the chromosomes is carried to all parts of the cell by one type of RNA called messenger RNA. Additional specialized RNA molecules are found inside the ribosomes, tiny bodies within the protoplasm that make proteins for the cell. Still other, smaller RNA molecules, called soluble RNAs play an active role in the synthesis of proteins by linking with the building blocks (amino acids) that form new protein. The soluble RNAs participate with specialized proteins (enzymes) and the ribosomes in following the instructions of the messenger RNA to build new protein molecules.
