DNA

- DNA is a polymer of nucleotides, each consisting of a nitrogenous base, a sugar, and a phosphate group - The nitrogenous bases can be adenine (A), thymine (T), guanine (G), or cytosine (C) - Sugar shape: Pentagon - Sugar: Deoxyribose - Shape of Nitrogenous base: Hexagon - Phosphate group shape: Circle - Locations: Nitrogen bases are rungs of ladder, sugar and phosphate are the outer portions of the ladder (^^ reference pic ^^) - Hydrogen bonds hold nitrogenous bases together (like when they pair up)
