Title: Recombinant DNA and Cloning The Impact of Biotechnology


1
Recombinant DNA and CloningThe Impact of
Biotechnology
  • Honors Genetics
  • Ms. Susan Chabot
  • Lemon Bay High School

2
Terms to Know
  • Restriction enzymes allow the DNA to be cut and
    spliced at VERY specific locations.
  • Vectors carriers of DNA molecules usually
    bacteria.
  • Plasmid circular DNA found in bacteria.
  • Recombinant DNA original carrier DNA
    introduced sections of DNA.
  • Clones when the bacteria divide, millions of
    copies of the original recombinant DNA are made.

Impact of Biotechnology
  • Biotechnology use of modified organisms or
    their products to enhance our lives.
  • Ethical Dilemmas
  • Patenting genes for ownership.
  • Patents offer scientists a chance to fund further
    research.
  • Limited availability of seeds to farmers.
  • Concentrates crop ownership to biotech companies,
    out of farmers hands.
  • Impact of GM foods in our own bodies.
  • Enough testing to identify risks/benefits?
  • Biotech and Medicine
  • Too much information too early?
  • Inability to get medical insurance.

Genetically Modified Plants
  • Resistance to insects, weeds, and viruses.
  • Enhanced oil content.
  • Delayed ripening.
  • GM foods can also be modified to increase the
    nutritional content of foods.
  • GM rice (golden rice) has been modified to
    contain more of the building blocks needed to
    produce Vitamin A.
  • Reduced blindness in poorer nations.
  • Over a dozen genetically modified crops approved
    to grow in the US.
  • 45 of US corn crop.
  • 85 of soybean crop.
  • 60 of processed food contains GM foods.

6
GM Animals
  • Transgenic animals are produced when one animals
    desired traits are recombined into another
    animal.
  • Human genes transferred into sheep for production
    of human proteins.
  • Embryo splitting has created commercially cloned
    GM organisms for 25 years.
  • Dont have to wait until adulthood to see if
    desired traits were inherited.
  • Cloned for desirable traits such as
  • High milk production.
  • Speed in race horses.
  • Transgenic animals.

Chapter 1 Essential Points
  • Page 4 1 Mendels Work.
  • Page 5 2 Chromosome Theory of Inheritance
  • Page 8 3 Central Dogma of Biology
  • Page 12 4 Biotech has revolutionized
    agriculture and pharmaceutical industries.
    Genetic testing and gene therapy has impacted how
    we treat and diagnose genetic diseases.
  • 5 Recombinant DNA
    technology has given rise to several new fields
    in science.
  • Page 14 6 Using model organisms allows us to
    use genetics and biotech to understand human
    health.
  • 7 Policies and regulations that
    pertain to genetic technology is lagging behind
    the technologies that are being introduced.
