IB Biology SL III Ryan Martucci Topic 2: The Chemistry of Life 2-10-03 8th period Sub-topic: 2.4 DNA Structure 2.4.1 2 Outline DNA nucleotide structure in terms of sugar (deoxyribose), base and phosphate. Genetic information is stored by nucleic acid. There are two kinds of nucleic acids: deoxyribose nucleic acid (DNA) and ribose nucleic acid (RNA). For the majority of organisms genetic information is stored in DNA in the nucleus and RNA are found in the cytoplasm. (Some viruses and prokaryotes store genetic information in RNA.) Nucleotides are complex molecules consisting of three molecules linked together: 1. a ribose pinto sugar, 2. a phosphate group, 3. a nitrogen bade. The sugar can be two possible sugars: 1. Ribose gives RNA with the molecular formula, C5H10O5, 2. Deoxyribose gives DNA with the molecular formula C5H10O4. The phosphate's molecular formula is H3PO4. Building a nucleotide: The nucleotide is usually represented as follows. Topic 2: The Chemistry of Life Sub-topic: 2.4 DNA Structure Page: 2 ...
