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.
Deoxyribonucleic acid (DNA) stores information for the synthesis of specific proteins. DNA has deoxyribose as its sugar. DNA consists of a phosphate group, a sugar, and a nitrogenous base. The structure of DNA is a helical, double-stranded macromolecule with bases projecting into the interior of the molecule.These two strands are always complementary in sequence.NA has a double helix structure. The outer edges are formed by alternating deoxyribose sugar molecules and phosphate groups, which make up the sugar-phosphate backbone. The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction.
