The question is: What type of molecule does not contain a phosphorus group in it? The answer is “nucleotides.” The phosphate group is found on the nitrogenous base of a nucleotide, and the hydroxyl group of the next sugar is attached to the phosphate group of the first nucleotide. The phosphodiester linkage is formed by the two phosphate groups. A polynucleotide can have thousands of phosphodiester links.
Phosphates, a chemical element found in nature and in many allotropic forms, are a common chemical element. They are found in the Earth’s crust, and make up the 11th-most abundant element in the body. The phosphate rocks are made up of a variety apatite minerals including chlorapatite.
