5 Matching questions

  1. DNA
  2. Conjugated Proteins
  3. NAM
  4. Southern Hybridization
  5. Unsaturated
  1. a antiparallel orientation of complimentary strands; DNA is supercoiled in the cells; denaturation and renaturation. ssDNA absorbs more light. RNA can compete with ssDNA hybridization.
  2. b one or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.
  3. c amino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.
  4. d N-acetyl muramic acid; important sugar acids in bacterial cell walls
  5. e diagnostic technique; denature and add a known fluoresced DNA. Don't have to know base structure.

5 Multiple choice questions

  1. m. wt. = 10^6-10^9; ribosomes, enzyme complexes, contractile systems, microtubules.
  2. fruit sugar mostly; but found in plants and animals also
  3. pyruvate, citrate, malate, etc.
  4. general formula (CH2O)n; subunits linked by glycosidic bonds; poly hydroxy aldehydes or ketones and their derivatives; functions- structural support, nutrient and energy.
  5. NAD+, NADP+, FAD, Coenzyme A

5 True/False questions

  1. Lipidsfats; long complex hydrocarbon chains; triglycerides, phospholipids in membranes, steroids like cholesterol; are non polar; function in energy storage and the structure of membranes; CH3(CH2)nCOOH n=14-22


  2. Complex lipidsFats or triglycerides= glycerol plus one or more fatty acids.


  3. Macromoleculesm. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.


  4. NucleosideSugar + Base + Phosphate; N-glycosidic bond- base; phosphodiester bond- phosphate


  5. NAGN-acetyl neuraminic acid; important sugar acids in bacterial cell walls.
