Title: Agriscience Applications


1
Agriscience Applications
  • Biotechnology

2
The Beginning
  • In your notebook write a definition for
    biotechnology
  • Without looking in the book

Life or living
Application of science to an industrial or

4
History
  • Biotechnology has been around since the beginning
    of time
  • Yeast to make bread rise
  • Bacteria to ferment sauerkraut
  • Bacteria to produce cheese, yogurt
  • Transform grain into alcohol

5
Biotechnology
  • Silage
  • Used for animal feed
  • Green grasses and grains stored in air tight
    containers
  • Converts sugars and starches to acids

6
The Genetic Connection
  • Genetics
  • Biology of heredity
  • Transmission of characteristics from an organism
    to its offspring through genes in reproductive
    cells
  • Gregor Mendel
  • Experimented with garden pea plants

7
The Genetic Connection
  • Genes
  • Components of cells that determine individual
    characteristics of all living things
  • Comprised of DNA
  • The Blueprint of cells and their successive
    cells

8
The Genetic Connection
Animal Cell
9
The Genetic Connection
  • Gene Mapping
  • Matching a gene to a trait
  • Determines what gene is responsible for certain
    traits
  • Examples
  • Tendency of baldness
  • Tendency of females to have twins
  • Height of plants

10
Application of Biotechnology
  • DNA Matching
  • Identifying the parents of offspring
  • Genetic engineering
  • Early 1980s
  • Modifies the genetic make-up of animals and
    plants
  • Movement of genetic information (genes) from one
    cell to another

11
Products of Genetic Engineering
  • Insulin
  • Treats diabetes
  • Herbicide resistant crops
  • BST (bovine somatotrapin)
  • Increases milk production
  • Ice-minus
  • Bacteria that retards frost formation on plants
  • Convert waste to fuel

12
Objective
  • Explore the structure of DNA as it is related to
    examples of agricultural plants and animals

13
DNA
  • Found in all living cells
  • All DNA is similar in structure and function
  • transmitter of heredity information

14
DNA
  • Deoxyribonulceic acid
  • Come in pairs of strands
  • connected by bases
  • Shape
  • double helix

15
DNA in Genetics
  • Gene Splicing
  • Removing and inserting genes into DNA
  • Alters a given characteristic
  • Examples
  • Alter a plants susceptibility to disease
  • Make a plant resistant to insects
  • Alter bacteria to increase meat production

16
Gene Mapping
  • The process of finding and recording the location
    of genes

17

18
Recombinant DNA
  • Improves animal and plant performance by
    manipulation
  • Alter microorganisms
  • Control
  • disease
  • insects
  • weeds
  • pest
  • Less use of chemicals more biological control
  • better for the environment

19
Concerns
  • Federal and state governments monitor use
  • Extensive testing
  • Laboratory to the greenhouse
  • Final testing is occurs outdoors prior to final
    approval
  • Final approval only after all phases are completed

20
Assignment
  • Organize a discussion group with two other
    people.
  • Explore four benefits and concerns of
    biotechnology
  • Record your benefits and concerns in your notes
    with an explanation
  • Provide the best solution for your concerns
  • Be ready to share your work
