Binary acids are acids that consist of two elements, usually hydrogen and one of the halogens. Oxyacids are acids that contain hydrogen, oxygen, and a third element (usually a nonmetal). uMany polyatomic ions are produced by the loss of hydrogen ions from oxyacids. Some examples include: sulfate from sulfuric acid, nitrate from nitric acid, and phosphate from phosphoric acid.
DNA or Deoxyribonucleic acid is a polymer that consists of monomers which have three components - a sugar (Ribose), a base (A,C,G,T) and a phosphate. Two such strands come together by virtue of hydrogen bonds between bases to form the double helical DNA structure. Now, these bases are hydrophbic, that is, they do not want to come in contact with water. This is ensured by the unique double hellical structure of DNA.
