    where the RNA polymeraseattaches. 
  3. What are some differences between DNA and RNA?
    • DNA is double-stranded,
    • RNA single-stranded
    • DNA contains Thymine,
    • RNA contains Uracil
    • DNA contains deoxyribose as its sugar 
    • RNA contains ribose
  4. Nucleic Acids are formed from _______? 
  5. What are Nucleotides made of 
    • sugar,
    • phosphate group
    • nitrogenous base. 
  6. Sugar and phosphate
    molecules combine to form a
    ______along the outside
    edge(s) of the molecule
  7. Give what each base pairs to
    • A with T (or U)
    • G with C 
  8. Of the bases, _____ and ______ are
    double ring structures called ______. 
    • Adenine
    • Guanine
    • purines
  9. Of the bases, _______ and ______ are
    single ring structures called ________.

    • Thymine
    • pyrimidines 
  10. One purine always pairs with one what 
  11. Why can C only pair with G and A only pair with T?
    Hydrogen bonds 
  12. Which carbons are the phosphate groups attatched to?
    #3 and 5 
  13. The arrangement of phosphates produces
    a __ and a __end of that side of the DNA
    molecule. The 3' end has __ ______
    attached to the __ _____
    • 3' 
    • 5'
    • no phosphate 
    • #3 carbon
  14. Give an example of antiparallel
    the opposite sides of the DNA molecule have the 3' and 5' end opposite from each other
  15. Enzymes only move from 
    5' to 3' 
  16. DNA must be able to make exact duplicates of
    itself in order for every cell to have the same
    DNA. This process is called 
    semiconservative replication
