Biotechnology review power point

  1. 1. Biotechnology ReviewQUIZ FEBRUARY 12TH
  2. 2. “ Ashley donated a regular body cell and Jesse donated an egg cell. Jesse’s egg cell had its nucleus removed. Ashley’s cell nucleus was transferred from the body cell into the egg cell. Cell division occurred and the new embryo was implanted into Madison, the surrogate mother. Madison eventually gave birth to the baby. Who does the baby resemble? ” Ashley
  3. 3. Who committedthe crime?Suspect #2
  4. 4. Goats that make spider silk is an exampleof…a. Genetic Engineeringb. Stem Cell Therapyc. DNA fingerprintingd. PCRA. Genetic Engineering
  5. 5. What might we be able to treatParkinson’s Disease with?A. Genetic EngineeringB. Stem CellsC. CloningD. Recombinant DNAB. Stem Cells
  6. 6. What is a genome?All of the genes within an organism
  7. 7. What is the Human GenomeProject?Mapping of all of the genes within humans
  8. 8. Why does DNA move through thegel during gel electrophoresis?Negative charge, moves towards positiveelectrode
  9. 9. Who is this? Dolly
  10. 10. Making an identical copy of an organism is known as what?Cloning
  11. 11. What is so great about a stemcell?Function has not yet been determined, candifferentiate into different cell types
  12. 12. What do we use to cut DNA?Restriction Enzymes
  13. 13. What organisms are restrictionenzymes naturally found in?Bacteria
  14. 14. What purpose do restrictionenzymes serve in bacteria?Protection from viruses
  15. 15. If a restriction enzyme cuts at thesequence CC/GG what kind ofends would we end up with on theDNA fragments?Blunt Ends
  16. 16. EcoRI recognizes the following sequence: G A A T T C CTTAAG What types of ends would this cut result in? Sticky
  17. 17. The longestfragment is inwhich lane?Lane D
  18. 18. The shortestfragment is inwhich lane?Lane A
  19. 19. What is the purpose of a DNA sizestandard?Gives known fragment lengths ofDNA
  20. 20. The left column is theDNA Standard of100, 50, and 10.What would theband lengths be inthe second column?About 75 and 50
  21. 21. What is a plasmid?Circular DNA in bacteria
  22. 22. EcoR1 recognizes the sequenceGAATTC. How many fragmentswould this piece of DNA be cutinto?2 cuts, so 3 fragments
  23. 23. What are the basic steps incloning?Place nucleus of somatic cell into egg cell thathas it’s nucleus removed, place into surrogate
  24. 24. What is the difference between anegg cell and a somatic cell?Somatic cell has full set ofchromosomes, egg cell has a half setof chromosomes
