However depending on the type of coal, it is composed of between 50-100% carbon, by mass, with the rest being Hydrogen, Nitrogen, Oxygen, and trace amounts of Sulfur.
The structure of nucleotide monomers. A nucleotide is made of a nucleobase (also termed a nitrogenous base), a five-carbon sugar (either ribose or 2-deoxyribose) depending on if it is DNA or RNA, and one or, depending on the definition, more than one phosphate groups.ithout the phosphate group, the nucleobase and sugar compose a nucleoside. The phosphate groups form bonds with either the 2, 3, or 5-carbon of the sugar, with the 5-carbon site most common. Cyclic nucleotides form when the phosphate group is bound to two of the sugar's hydroxyl groups.
The three subunits of a nucleotide are a nitrogenous base, a sugar and a phosphate group. Nucleotides are the building blocks of DNA and RNA molecules. One nitrogenous base, known as purine, is comprised of adenine and guanine. The other nitrogenous base is pyrimidine, which is cytosine and thymine. These bases combine to form DNA. RNA formation is slightly different, as uracil is substituted for thymine. Deoxyribose is the sugar subunit in a DNA molecule, while ribose is the sugar subunit of an RNA molecule. Nucleotides form nucleic acids, which are organic compounds that are found in every cell.
