are nucleotides composed of phosphoric acid
Nucleotides are organic molecules that serve as the monomers, or subunits, of nucleic acids like DNA and RNA. The building blocks of nucleic acids, nucleotides are composed of a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.Thus a nucleoside plus a phosphate group yields a nucleotide.ucleic acids are polymeric macromolecules made from nucleotide monomers. In DNA, the purine bases are adenine and guanine, while the pyrimidines are thymine and cytosine. RNA uses uracil in place of thymine. Watson and Crick describe structure of DNA1953. Photo: Model of DNA molecule. In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA.atson and Crick describe structure of DNA1953.

ADP and ATP. It is possible for the nucleotides (which are composed of a base, a sugar unit, and a phosphate unit) to combine with additional phosphate units (or phosphoric acid units) to make di phosphates and tri phosphates.t is possible for the nucleotides (which are composed of a base, a sugar unit, and a phosphate unit) to combine with additional phosphate units (or phosphoric acid units) to make di phosphates and tri phosphates. Nucleic acids Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. They are the vehicles of genetic inheritance.Nucleic acids are condensation polymers of nucleotides.ormation of a polynucleotide Nucleic acids are the 'building blocks' of DNA and RNA. The structure of DNA DNA is formed from two polynucleotide chains. Each chain has a helical structure (a helix), in other words the molecule is coiled like a spring. nu·cle·o·tide.

Nucleotides. the basic units of nucleic acids. Some nucleotides are coenzymes or other biologically active compounds. Each nucleotide is composed of a nitrogenous base, usually purine or pyrimidine; a carbohydrate, either ribose or deoxyribose; and a phosphoric acid residue.ucleotides with three phosphoric acid residues—nucleoside triphosphates—are high-energy compounds; these are the direct precursors in the biosynthesis of nucleic acids.

The structure of DNA DNA is formed from two polynucleotide chains. Each chain has a helical structure (a helix), in other words the molecule is coiled like a spring. Compounds that contain many nucleotides are called polynucleotides, or nucleic acids. A nucleotide can contain nitrogenous bases other than purines and pyrimidines, for example, nicotinamide mononucleotide is a compound of the base nicotinamide with a ribose and a phosphoric acid residue.ucleotides with three phosphoric acid residues—nucleoside triphosphates—are high-energy compounds; these are the direct precursors in the biosynthesis of nucleic acids. In this case adenosine combines with the phosphate (or phosphoric acid) to form the nucleotide adenosine monophosphate. This is a dehydration reaction in water is released and a phosphate ester bond is formed.ucleotide Structure. Phosphate. Another important thing to keep in mind as we look at the structure of nucleic acids is that two of the oxygens (or OHs) of the phosphate group (or phosphoric acid molecule) will be used to bond this unit to sugar molecules.
