These are: adenine, cytosine, guanine, thymine, and uracil. Strings of nucleotides are bonded to form spiraling backbones and assembled into chains of base-pairs selected from the five primary, or canonical, nucleobases.
Both play a crucial role in directing protein synthesis. This gives the RNA and DNA their unmistakable 'ladder-step' order of nucleotides within their molecules. From the inner workings of the cell to the young of a living thing, they contain and provide information via the nucleic acid sequence. In turn, they send and express that information inside and outside the cell nucleus. These acids are very common in all living things, where they create, encode, and store information in every living cell of every life-form on Earth. They carry information in cells and make up genetic material. Nucleic acids are chemical compounds that are found in nature. If the sugar is ribose, the polymer is RNA if the sugar is deoxyribose, a version of ribose, the polymer is DNA. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. Nucleic acids are biopolymers, macromolecules, essential to all known forms of life. Nucleic acids RNA (left) and DNA (right).
