Title: Biotechnology Unlocking the secrets of life


1
BiotechnologyUnlocking the secrets of life
2
What is Biotechnology?
  • Definition
  • The use of living organisms to make or improve a
    product
  • Bio (life)
  • technology (the application of knowledge for
    practical use

3
Where did it begin?
  • Ancient bread baking
  • Wine brewing
  • Cheese making
  • Yogurt fermentation
  • Animal and plant breeding

4
Biotechnology Today
  • Focuses on how to change microorganisms, plants
    and animals
  • Scientist isolated and made changes to DNA in the
    early 1970s
  • DNA carries the Blueprint
  • Genes are units of DNA

5
Techniques
6
Genetic Engineering
  • Manipulation of genes is called genetic
    engineering or recombinant DNA technology
  • Removes gene(s) from one organism and either
  • Transfers them to another
  • Puts them back in the original with a different
    combination
  • Transgenic

7
Techniques
  • Genetic Mapping
  • Locating specific genes within heredity material
  • Tissue Culture
  • Modified cells can grow into whole plants
  • Biofermentation
  • Mass production of modified microorganisms
  • Cloning
  • Reproducing genetically identical animals

8
Biotechnology in Agriculture(Plants)
  • Crops
  • Built in insect and herbicide resistance
  • Built in tolerance to environmental conditions
  • Improved color and quality
  • Pharmaceuticals
  • Plants that produce edible vaccines
  • Food
  • Improved taste and nutrition
  • Improved handling qualities

9
Biotechnology in Agriculture(Plants)
  • Industrial
  • plants that produce plastics, fuels, and other
    products
  • plants for environmental cleanup
  • Other
  • pesticides made from naturally-occurring
    microorganisms and insects

10
Biotechnology in Agriculture(Animals)
  • Breeding
  • Disease tolerance
  • Exact copies of desired stock
  • Increased yields
  • Health
  • Microorganisms introduced into feed for
    beneficial purposes
  • Diagnostics for disease and pregnancy detection
  • Animals engineered to to produce organs suitable
    for transplantation into humans

11
Biotechnology in Agriculture(Animals)
  • Food
  • Increased milk production
  • leaner meat in pork
  • growth hormones in farm-raised fish that result
    in earlier market-ready fish
  • Pharmaceuticals
  • Animals engineered to produce human proteins for
    drugs, including insulin and vaccines

12
Assignment
  • Develop a timeline of events outlining advances
    in the field of biotechnology. You may use the
    World Wide Web in the Career Center to search for
    these events.
  • Your timeline should have at lease five events.
  • The search engine www.google.com is a good start.

13
History of Biotechnology
  • 1860s-Botanist Gregor Mendel recognizes heredity
    information is stored in units (now called genes)
  • 1870s-chromosomes are discovered
  • 1953-DNA Double Helix is discovered by James
    Watson and Francis Crick (England)

14
History of Biotechnology
  • 1968-a process was developed for identifying
    chromosomes (Switzerland)
  • 1973-First successful combining of DNA from
    unrelated organisms (recombinant DNA) (USA)
  • 1978-First test tube baby (Louise Brown) was born
    in England

15
History of Biotechnology
  • 1984-Sheep and goat embryo cells are fused
    together to create a sheep-goat
  • 1986-Light-producing gene of firefly is
    transferred to tobacco creating tobacco plants
    with glowing leaves
  • 1987-calf cloned from an embryo

16
History of Biotechnology
  • 1991-sheep created that makes drug in milk to
    treat cystic fibrosis
  • 1994-first transgenic food approved (Flvr Savr)
    tomato
  • 1996-goat injected with a human gene produces an
    anticancer drug
  • 1997-Adult sheep cloned (Dolly)

17
Industry
  • In 1998 there were 1,300 biotechnology companies
    in the Unites States
  • small start up companies
  • one product or service
  • large multinational corporations
  • combine research and production

18
Industry
  • In 1997 the overall biotechnology sales increases
    20
  • 13 billion dollar industry
  • Over 93 billion dollars invested

19
Careers
  • In 1998 biotechnology included about 140,000 jobs
  • Jobs for high school graduates to PhDs
  • Provides over 17,000 jobs in North Carolina
  • 850 million dollar payroll

20
Career Examples
  • Laboratory work
  • working on gene maps
  • growing plants from cells
  • working with animal embryos
  • Experimental Farms
  • Field jobs
  • Industry jobs
  • manufacturing
  • regulatory affairs (FDA, USDA)
  • sales

21
Education
  • High School Courses
  • Basic Biology
  • Agriculture
  • Biotechnology
  • Post-secondary
  • Biology
  • Microbiology
  • Genetics
  • Biochemistry

22
Education
  • North Carolina has an online biotechnology center
  • Information on NC Biotechnology
  • Educational Opportunities
  • News
  • Hot Topics
  • www.ncbiotech.org/

23
Assignment
  • Research two different careers related to
    biotechnology
  • Find information regarding
  • Salary
  • Education
  • Job Description
  • Job Demand
  • Write a one paragraph summary for each career
  • Keep the summaries in your notes
