Using molecular genetics for practical purposes

3. Must first identify the genome of the organism= all genes within the species
Human Genome Project: 1990’s- Thought there were 100,000 genes. Only found 30,000.

4. Cloning Pieces of desired plant placed into growth medium
-Food Supply (Salmon, fruits, veggies, corn)
Somatic cell nuclear transfer

5. Stem Cell
Undifferentiated cells (early development) can “switch” on DNA and “tell” cell what to be.
May be a cure for Parkinson’s, “growing” organs, tissues for
burn treatment,
paralysis
Controversial
2types: adult and
embryonic

6. Gene Therapy
Treat genetic disorder by replacing “bad” gene with a “good” one.
Designing medications specific to a person’s genetic code
Could cure: Hemophilia,
Cystic Fibrosis, Muscular
Dystrophy

7. PCR: Polymerase Chain Reaction
In past genetic tests on small samples used up most or all of the DNA
Makes many copies of small amounts of DNA for testing.

8. DNA Profiling Use to be called DNA Fingerprinting
Using genetic code markers to identify people
Used for paternity tests and test DNA found at crime scenes.
Gel electrophoresis- Bar code of genetic markers.

9. 1970: Bacteria E. coli makes ENDONUCLEASES (enzymes) Cuts viral DNA in the same place EVERYTIME. “Sticky Ends” Results are: smaller pieces of DNA, some the same size
GAATTC
CTTAAG

11. Paternity Forensics

12. Recombinant DNA Most promising for curing disorders.
Making human proteins using bacteria:
- Insulin: treatment of diabetes
- Clotting Factor: hemophilia
- HGH: height disorders
Combines genes that code for human proteins with the plasmid DNA of E.coli…which now synthesizes the human protein

14. GMOs (or “genetically modified organisms”) are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering, or GE.
This relatively new science creates combinations of plant, animal, bacteria and viral genes that do not occur in nature or through traditional crossbreeding methods.
Virtually all commercial GMOs are engineered to withstand direct application of herbicide and/or to produce an insecticide.
