  1. Secondary
  2. Macromolecules
  3. DNA
  4. Nucleoside
  5. Competitive Inhibition
  1. a m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
  2. b Sugar + Base
  3. c occupy the active site
  4. d antiparallel orientation of complimentary strands; DNA is supercoiled in the cells; denaturation and renaturation. ssDNA absorbs more light. RNA can compete with ssDNA hybridization.
  5. e The localized twisting and folding of the polypeptide chain. A specific orientation in space. Two main types: the alpha helix and the beta sheet. Helix- parallel some of the strongest; alpha keratin-nails; spiderwebs. Pleated sheet- anti-parallel; Beta keratin- silk. 18% of all proteins are one of these two shapes; others are random coiling

5 Multiple choice questions

  1. one or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.
  2. glucose and fructose; bad for teeth
  3. 10s-100s of polysaccharides; storage molecules, i.e., cellulose, chitin, glycogen; linear or branched; made of similar or different subunits.
  4. DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
  5. proteins and RNA

  3. Saturatedone or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.


  4. Lactoseglucose and galactose


  5. Ketosefruit sugar mostly; but found in plants and animals also
