It is not, therefore, surprizing that nothing of the original book remains in the current edition. Forces holding duplexes together include hydrogen bonds between the bases of each strand that, like the hydrogen bonds in proteins, can be broken with heat or urea. Nucleic acids are formed by the combination of nucleotide molecules through sugar phosphate bonds known as phosphodiester linkages. Sugars and phosphates are linked through the esterphosphate bond created the common backbone that plays a structural role.

Although the nucleic acids were first discovered in 1868, by friedrich miescher working with pus cells obtained from discarded surgical bandages, it was not really until the early 1940s that the chemistry and biology of the nucleic acids were set on firm foundations. The hydrogen bonds between the base pairs are broken, and the bases are exposed. When the first edition of this book was published in 1950, it set out to present an elementary outline of the state of knowledge of nucleic acid biochemistry at that time and it was the first monograph on the subject to appear since levenes book on nucleic acids in 1931. On the other hand, the sequence of bases along a nucleic acid chain carries the genetic information. They are composed of nucleotides, which are the monomers made of three components. The sequence of bases attached to the sugar units of the backbone changes each nonterminal p i not at the ends of the backbone is bonded to 2 sugar molecules via a 3,5phosphodiester bond one phosphoester bond between.
