Thus, nucleic acids are defined as large macromolecules that store, encode and transmit genetic data from one generation to another. The term “nucleic acid” is used to describe these large molecules in our cells that hold so much vital information about us, our lineage, and our genetic setup. These are made of polymers of repeating units, with acidic properties. CANTOR New York Preface This monograph is based on a review on polynucleotide structures written for a book series in 1976.Much like you would record your favorite songs on a tape in the 90s, so is our genetic information encoded in our cells, in the form of RNA and DNA. In some cases the availability of texts in active research areas should help stimulate the creation of new courses. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Textbooks in these subjects usually have to be written by scientists actually involved in the research which is advancing the field. The most serious needs occur in fields that are rapidly changing. However, some areas of chemistry, especially many of those taught at the grad uate level, suffer from a real lack of up-to-date textbooks. Some fields like basic biochemistry, organic reaction mechanisms, and chemical ther modynamics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. New textbooks at all levels of chemistry appear with great regularity.
