2  Definition:  Use of living organisms (microorganisms) to make new products or carry out new processes (solve problems).  New product  Yogurt  New Process  Tissue culture - propagation method that rapidly multiplies plants

3  Use of yeast to make bread rise.  Use of bacteria to produce various kinds of cheeses and other dairy products.  Use of microorganisms to transform fruit or grains into alcoholic beverages.  Use of bacteria to “produce” silage  E.coli bacteria used to produce insulin.  It became one of the first commercial products created by genetic engineering.

4  Austrian monk, Gregor Johann Mendel  discovered the effect of genetics on plant characteristics with his experimentation with garden peas  Heredity  transmission of characteristics from an organism to its offspring through genes in reproductive cells

5  Genes  Segments of double stranded DNA that determines the individual characteristics of living things ▪ Ex: plant height at maturity, flower color, ears of corn per stalk.  Generation is the offspring, or progeny, of common parents.

6  Chromosome  structure that holds the genetic information of a cell  DNA is wound tightly to form the chromosome.  DNA  deoxyribonucleic acid  coded material in all cell nuclei that determines what that cell and its successive cells will become  Shaped like a twisted ladder called a double helix

7  Gene  A small section of DNA.  There are thousands of genes on a strand of DNA.  Gene mapping  The process of finding and recording the locations of genes  Bases  Similar to rungs of a ladder that hold the two sides of the DNA strands together

8  The bases are:  Adenine (A) - only pairs with “T”  Thymine (T) – only pairs with “A”  Guanine (G) – only pairs with “C”  Cytosine (C) – only pairs with “G” ▪ Example: ▪ A – T ▪ G – C ▪ T - A  The sequence of the bases between the DNA strands is the code by which a gene controls a specific trait  Example: ▪ baldness in humans, tendency of female goats to have twin offspring

10  Process of moving genetic information in the form of genes from one cell to another.  Developed in the early 1980’s  Gene splicing or Recombinant DNA technology  process of removing and inserting genes from one organism and inserting them into the DNA of another 1.Alter a plant’s susceptibility to disease. 2.Make a plant resistant to insects. 3.Process in animals is newer and not as well developed techniques exist yet.

11  Known as “micropropagation” in plants  Creating an exact genetic duplicate of another organism.

12  One of the oldest methods of biological detection  Uses plants, animals and microbes to warn us about pollutants in the environment

13  A set of techniques that use living organisms to clean up toxic wastes in water and soil.

14  Adding nutrients such as nitrogen and phosphorus to stimulate the growth of naturally occurring beneficial microbes for faster, more efficient work.

15  The process of plants absorbing or immobilizing pollutants.  First tested actively at sites in the 1990’s.

16  The processes used in improving the efficiency of reproduction and production.  These are considered the more conventional (traditional) uses of biotechnology.

17  Fuels composed of or produced from biological raw materials

18  Joining of DNA from two different species and inserted into host organism  Improve plants’ and animals’ performance through the manipulation of genes.  Alter characteristics or performance of microorganisms  Great potential for controlling disease, insects, weeds, and other pests  Less use of chemical pesticides  Potential for helping clean the environment

19  Safety  State and federal government monitor the development of newly developed biotech crops  Consumer resistance remains high due to safety of the environment and human health concerns  Some people can create a fear of the unknown  Labeling of genetically modified organisms (GMO) foods ▪ many people feel if a product is safe it should be labeled  Effect GMO’s may have on biodiversity  Ethics  System of moral principles that defines what is right and wrong in a society  The ability to manipulate genetics of living organisms raises important ethical questions about how biotechnology should be used

21  Herbicide – tolerant soybean  Also known as “RoundUp Ready Soybeans”  contains a gene that provides resistance to one or two broad spectrum herbicides.  Other RoundUP Ready crops: Canola, Corn, Cotton, Alfalfa, Lettuce, Potatoes, Sugar Beets, and Tomatoes  Insect- resistant corn (Bt corn)  contains a built-in insecticidal protein from a naturally occurring soil microorganism (Bt – Bacillus thuringiensis) that gives season- long control of corn borers.

22  High Oleic Peanut  genetically modified to produce nuts in high oleic acid that results in longer life for nuts, candy and peanut butter  High Oleic Sunflower  modified to produce sunflower oil that is low in trans-fatty acids  Delayed- ripening tomato  the longer shelf life has commercial advantages in harvesting and shipping

23  Also known as micropropagation  Using a very small, actively growing part of the plant to produce a large number of new plants  Example: African violets
