You can test out of the 3. The sugars found in nucleic acids are pentose sugars; a pentose sugar has five carbon atoms. Similarities. A Structure for Deoxyribose Nucleic Acid," published in Nature in 1953, the two scientists described the double-helical form of the molecule, shaped like a twisted ladder, in which each rung is made up of four nucleotides: adenine, thymine, cytosine, and guanine (typically abbreviated as A, T, C, and G). DNA, or deoxyribonucleic acid is a polymer formed of many nucleic acids. More... Molecular Weight. It is evident from the name that it is a deoxy sugar. Deoxyribose is the pentose sugar of DNA with five carbon atoms. As the name implies, deoxyribose is a deoxygenated sugar, meaning it is derived from ribose sugar by the loss of an oxygen atom. The backbone structure is independent of which particular bases are attached to the individual sugars. Deoxyribose vs. Ribose. Nucleotides can have either a deoxyribose or ribose sugar as the 5-carbon sugar, and depending on which sugar is used, the nucleic acid that is formed will be either DNA or ribonucleic acid (RNA). An explicit range of sugar conformations is associated with A-, B-, and Z-form DNA duplexes and, within a determined family (i.e., B-form DNA), local structural variations correlate with the specific sugar pucker. Why is the use of thymine rather than uracil in DNA essential for the correct repair of deaminated cytosine in DNA? Its backbone is a chain of 5 carbon atoms – 4 of them carry an OH group, the 5th an oxygen atom that is attached by a double bond. This simple sugar is used in medicinal practice to improve exercise performance and increase muscle energy. The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group.
