Phosphoesters form the backbone of DNA molecules. They consist of a nitrogenous base attached to a sugar-phosphate backbone. The deployment of IPv6 in the Internet backbone continued. The temples formed the backbone of the economy. The remaining signals correspond to carbons characteristic of the xanthine backbone. It formed the basis of the Internet's historic multicast backbone, Mbone. It binds the minor groove of DNA and cleaves the phosphodiester backbone. It specifies the order of side-chain groups along the linear polypeptide "backbone". Lords and kings supported entourages of fighters who formed the backbone of the military forces. It is difficult to pull off without controlling some of the Internet backbone. In molecular biology, several analogues of the sugar backbone exist. Twin helical strands form the DNA backbone. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Most universities and research centers migrated to the Internet2 educational backbone. It is the sequence of these four nucleobases along the backbone that encodes biological information.
