DNA structure | The "spiral staircase" structure. The two sugar-phosphate backbones twine around each other while complementary bases (colored bars) face each other on the inside of the double helix. |
double helix | The steplike connections between the backbones are pairs of nitrogenous bases. / Across from a purine on one backbone, there is a pyrimidine on the other. |
comparison of DNA to RNA | DNA is a double helix, RNA consists of only one nucleotide chain / sugar in RNA is ribose instead of deoxyribose / it has no thymine; a base called uracil (U) takes its place. |
semiconservative | duplication of DNA so that each daughter cell is given a complete copy of its genes |
