Structure of Nucleic Acids Phosphate Group - One of three components of a nucleotide, comprised of a central phosphorous surrounded by four oxygens. The phosphate links to the sugar group, carries a negative charge because of the chemical interaction between phosphorous and oxygen, and forms the exterior of the phosphate backbone. Phosphodiester linkage - In a polynucleotide, refers to the bond between the 3' hydroxyl of a sugar group in a nucleotide and a phosphate group attached to the 5' carbon of another sugar group. Pitch - In a helix, refers to the vertical distance traveled in one full turn (360 degrees of twist). Primary Structure - In DNA and RNA, refers to the linear sequence of base pairs or amino acids in a polynucleotide chain. Purine - One of two categories of nitrogen base ring compounds found in DNA and RNA. A purine is a nine-membered double ring composed of one five-membered joined to a six membered ring containing four nitrogens. See pyrimidine. Pyrimidine
