1. KEY CONCEPT DNA fingerprints identify people at the molecular level.

2. A DNA fingerprint is a type of restriction map. DNA fingerprints are based on parts of an individual’s DNA that can by used for identification. based on noncoding regions of DNA noncoding regions have repeating DNA sequences number of repeats differs between people Gel electrophoresis separates the sequences into “bands”

3. (mother) (child 1) (child 2) (father) DNA fingerprinting is used for identification. DNA fingerprinting depends on the probability of a match. Many people have thesame number ofrepeats in a certainregion of DNA. The probability that two people share identicalnumbers of repeats inseveral locations isvery small.

5. evidence in criminal cases

6. paternity tests

7. immigration requests

8. studying biodiversity

10. Entire organisms can be cloned. A clone is a genetically identical copy of a gene or of an organism. If you could clone your favorite pet, would you? Why or why not?

12. bacteria (binary fission)

13. some plants (from roots)

15. nucleus is removed from a fertilized egg cell

17. organs for transplant into humans

18. save endangered species

19. Cloning raises concerns. Like what?

20. low success rate

21. clones “imperfect” and less healthy than original animal

23. (bacterial DNA) New genes can be added to an organism’s DNA. Genetic engineering involves changing an organism’s DNA to give it new traits. What genes would you like to incorporate into your favorite pet? Genetic engineering is based on the use of recombinant DNA. Recombinant DNA contains genes from more than one organism.

25. plasmids are loops of DNA in bacteria

26. restriction enzymes cut plasmid and foreign DNA

29. gene inserted into plasmid

30. plasmid inserted into bacteria

31. bacteria express the gene

32. Transgenic plants are common in agriculture.

33. transgenic bacteriainfect a plant

34. plant expressesforeign gene

36. transgenic mice used to study development and disease

38. possible long-term health effects of eating GM foods

45. Review DNA fingerprinting is used for identification and determining relationship A clone is a genetically identical copy of a gene or of an organism – cloning occurs in nature Cloning has potential benefits and raises concerns Genetic engineering involves changing an organism’s DNA to give it new traits. A transgenic organism has one or more genes from another organism inserted into its genome Transgenic organisms are already being used both in agriculture and scientific studies Transgenics has potential benefits and raises concerns
