  4. Nucleic Acids
  5. Southern Hybridization
  1. a diagnostic technique; denature and add a known fluoresced DNA. Don't have to know base structure.
  2. b DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
  3. c m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
  4. d Biological catalysts- specific for a chemical reaction; not used up in that reaction; Apoenzyme: protein.
    Co-factor: non-protein component; Coenzyme- organic cofactor (NAD, FAD); Holoenzyme-Apoenzyme + cofactor.
  5. e all hydrocarbons have CH2 units (bad for health); animals
