BIOL 200

  1. RNA?
    • ribonucleic acid 
    • relatively small compared to DNA
  2. DNA
    • deoxyribonucleic acid
    • Relatively big compared to RNA
  3. Nucleiottide Monomers?
    • -Provide acidic characters 
    • -Under intracellular conditions the phosphate group is negative
    • -Phosphate group linked by phosphodiester bond to a pentose sugar molecule
    • -Pentose is linked to a nitrogen and carbon containing ring structure referred to as a base 
  4. Whats the difference with DNA and RNA 
    RNA has a hydroxyl group on the 2' carbon when DNA has only a H
  5. Purines?
    Adenine and Guanine 
  6. Pyrimidines?
    • Uracil
    • Thymine 
    • Cytosine
  7. Nucleioside?
    Sugar and base without phosphate group

  10. Image Upload 3
    guanine 
  11. Image Upload 4
    thymine
  12. Image Upload 5
    Uracil
  13. Amino acids are building blocks for...
    polypeptides
  14. What determines the properties of an amino acid
    R group
  15. Which are two possible types of isomers 
    D and L isomers. L isomers dominate D isomers
  16. What are people doing with D isomers 
    Making pesticides and such with artificial polypeptides of D isomers because most organism dont know hoe to break them down. 
  17. Cysteine (cys or C)
    • Can form disulfide bonds with other cysteines
    • intra and inter-cross linking 
    • stabilizes folded structure 
  18. When you think rigid structure?
    Proline(Pro or P) and Glysine(Gly or G)
