Each&nbsp;nucleotide&nbsp;consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon)&nbsp;sugar, which is in turn attached to a&nbsp;phosphate&nbsp;group. Each nucleic acid contains four of five possible nitrogen-containing&nbsp;bases:&nbsp;adenine&nbsp;(A),&nbsp;guanine&nbsp;(G),&nbsp;cytosine&nbsp;(C),&nbsp;thymine&nbsp;(T), and&nbsp;uracil&nbsp;(U). A and G are categorized as&nbsp;purines, and C, T, and U are collectively called&nbsp;pyrimidines. All nucleic acids contain the bases A, C, and G; T, however, is found only in DNA, while U is found in RNA. The pentose sugar in DNA (2\u2032-deoxyribose) differs from the sugar in RNA (ribose) by the absence of a&nbsp;hydroxyl group&nbsp;(\u2015OH) on the 2\u2032&nbsp;carbon&nbsp;of the sugar ring. Without an attached phosphate group, the sugar attached to one of the bases is known as a&nbsp;nucleoside. The phosphate group connects successive sugar residues by bridging the 5\u2032-hydroxyl group on one sugar to the 3\u2032-hydroxyl group of the next sugar in the chain. These nucleoside linkages are called phosphodiester bonds and are the same in RNA and DNA.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Basic structure Nucleic acids are polynucleotides\u2014that is, long chainlike molecules composed of a series of nearly identical building blocks called&nbsp;nucleotides.
