What is Biotechnology Biotechnology? Biotechnology: the branch of molecular biology that studies the use of microorganisms to perform specific industrial processes; "biotechnology produced genetically altered bacteria that solved the problem"
3
Biotechnology Introducing foreign DNA into an organism in order to modify the organism’s DNA
4
Areas of Use Agriculture Medicines Genetics Food science Criminal Investigations
5
Biotechnology and Agriscience
6
Agriculture Food crop manipulations Disease-resistant crops Biological Pesticides
7
Agricultural Positives More Food Produced Less Hunger Increased Profit Needs less land Negatives Biodiversity Human Health Nature
8
Genetically Modified Organism Is an organism whose genetic material has been altered using genetic engineering techniques.organismgenetic engineering These experimental combinations of genes from different species cannot occur in nature or in traditional crossbreeding. 6/8/2016
9
Impact of Biotechnology Genetically modified organisms (GMOs) are consumed by millions of people (especially Americans) EVERY DAY. – Almost 56% of all soybean plantings worldwide are genetically engineered (much higher in the US)
10
Impact of Biotechnology Genetically modified crops were produced on more than 167 million acres in 18 countries in 2003, a 15% increase from 2002 – The US was the largest single producer with more than 60% of the total acreage in production.
11
Transgenic Is a gene or genetic materialgenegenetic that has been transferred naturally, or by any of a number of genetic engineering genetic engineering techniques from one organism to another. The introduction of a transgene has the potential to change the phenotype of an organism.phenotype 6/8/2016
12
Plant Science Wide scale production of transgenic plants impacting horticulture
13
Farming & the Environment Reduces the use of pesticides Decreases soil erosion Helps protect water Conserves land & fossil f uels
14
Farmers Increases crop yields Reduces farmer production costs Decreases farmer exposure to pesticides Improves farming efficiency
15
Efficiency Must keep the cost of improving products as low as possible Biotech results in greater efficiency
16
Animal Science Increased use of methods of in vitro fertilization and artificial insemination improve selected breed programs
17
Environmental Science Use of biotechnology techniques in environmental science for cleaning contaminants and protecting endangered species – Bioremediation-use of natural organisms to clean contaminants – Example Gulf Oil Spill
18
6/8/2016 Did you know that the key to ridding the oceans of oil may already lie in underneath its surface? Bioremediation — using naturally present microorganisms to clean up oil spills — makes use of bacteria living in the ocean who actually “eat” the oil when it enters their natural habitat. Adding sulfate or nitrate fertilizers to the microorganism population causes them to multiply beyond their natural state and eat up the toxic metals invading their home at up to five times the rate that they would without assistance.
19
Problems with Biotechnology in Agriculture
20
Problems with Biotechnology Transfer of genes found in transgenic organisms to natural populations. – Terminator genes have been used to minimize this risk
21
Unexpected impacts of genetically modified organisms and biotechnology processes on other organisms and the environment Problems with Biotechnology
22
Expense of the utilization of many biotechnology techniques – Cost of producing transgenic animals (There are transgenic fish, but no livestock yet.) Problems with Biotechnology
23
Concerns over the safety and ethics of incorporating GMO’s into food for human consumption – Allergens – Example: The use of Star link corn in taco shells not approved for human consumption Problems with Biotechnology
24
Lack of education among both consumers and producers concerning biotechnology processes and products Problems with Biotechnology
25
Health/Agri-medicine Pharming-the creation of plants and animals capable of producing medical substances The use of biological barriers to prevent the spread of harmful microorganisms that could contaminate food sources
26
Health/Agri-medicine DNA analysis/paternity testing has emerged as a technique to test the genetic ancestry of animals
27
Medicines Vaccines Tissue Replacement – Ex Organs grown to replace your own Genetic Origins of Diseases – Ex. Is it linked to your genetic make-up Medicine – Ex. Penicillin/Alexander Fleming – Human Insulin for diabetes
28
Genetics Being able to alter genes Cloning Genetically engineered babies Link disease genetically
29
Cloning Process of producing a new organism from cells or tissues of existing organism. 1997 cloned sheep – “Dolly” in Edinburgh Scotland
30
Genetic Engineering Changing the genetic information in a cell Specific trait of one organism may be isolated,cut, and moved into the cell of another organism
31
DNA Finger Print A technique used especially for identification (as for forensic purposes) by extracting and identifying the base-pair pattern in an individual's DNA —called also DNA typing
32
Criminal Investigation DNA fingerprinting – Evidence that person was involves in a crime. Data Bases – Allows criminal investigator to have access to people’s DNA to compare to evidence
33
DNA Finger Print Forensic Investigator – Criminal Activity Police – Criminal Activity – Identify a Person
34
6/8/2016 Careers Research – Labortory Agricultural – Development of plants and animals Biology Genetics Forensic Investigator Biotechnician – Create safe products for consumers Medicine – Doctor Predict Patients genetic health
35
6/8/2016 Ethical Issues Benefits of technology outweigh the harm Example of some issues – Decreased biodiversity – Cloning – Designer babies – Companies requiring – Selective Breeding – Environmental Harm – Super Germs
36
Impact of Biotechnology The NC Biotechnology Center predicts that the biotechnology industry in the state will contribute more than $25 billion in annual income each year within the next 25 years.
37
6/8/2016 North Carolina Over 400 companies great impact on economy Improved crop yield Created disease resistant crops(greatest benefit) Improved livestock producing higher quality meat Creates Jobs
38
6/8/2016 North Carolina 237,665 jobs $59 billion in North Carolina business volume $1.73 billion in taxes generated for state and local government A thriving industry with more than 500 companies
