2
Science – the study of the natural world Technology – the development of equipment needed to study the sciences. Science & Technology spur each other forward
3
Biotechnology or biotech is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use"
4
Should we do it? should we manipulate nature? Bio ethics
5
Biotechnology has applications in four major industrial areas: health care (medical) Gene therapy Immunology Medications Diagnostic Testing Cell & Tissue Cultures
6
Who decides??? Are there boundaries? who decides? How far is too far? Should we develop the technology & not use it? Is it different to manipulate plants and animals than to manipulate humans? Should personal decision be honored ? Bioethics
7
There are three basic kinds of biotechnology tools: working with cells, working with proteins, and working with genes. Working with cells Working with proteins Working with genes
8
Biotechnology Helps meet human needs Food, clothing and shelter Plants and animals are used in manufacturing food, clothing and materials for shelter
9
Biotechnology Used to make products more useful or desirable Ex: conversion of milk into cheese or yogurt Also used in maintaining a good environment that promotes our well being. Using scientific processes to get new organisms or new products from organisms.
10
Highly-developed Crop Varieties Enhanced growth Higher yields Drought resistant Cope with less ideal soils/harsher conditions Improved taste, texture, appearance Insect resistant Biotechnology in Agriculture
12
Potatoes, tomatoes, lettuce rice to produce insulin & for vaccines (a future of homegrown, edible vaccines??? – global access, no syringes, no medical waste) Biotechnology in Agriculture
13
Biotechnology has applications in four major industrial areas: crop production and agriculture Selective breeding Hybridization Pest resistant
14
Biotechnology has applications in four major industrial areas: non food (industrial) uses of crops – biofuels #1 concern re biomass for fuel?
15
Agricultural View All of the applied science based operations in producing food, fiber, shelter, and related products. Milk production New horticultural and ornamental plants Wildlife, aquaculture, natural resources and environmental management
16
Biotechnology in Animals breeding programs by directing selection of superior animals Biotechnology in Agriculture
17
Animal Biotech Improve animals or the products they produce Animals may be used to produce products that promote human health Increase productivity Pigs engineered to produce human hemoglobin
18
plant-based, Earth friendly products Biotechnology in Agriculture Finding new uses for foods Oils seed for detergents (cuts down on petro use)
19
Biotechnology in Agriculture
20
plant-based Henna Art Biotechnology in Agriculture
21
Bioremediation and biodegradation engineer and adapt organisms, especially microorganisms, in an effort to find sustainable ways to clean up contaminated environments. Biotechnology in Agriculture
22
Organismic Biotech Help the organism live better or be more productive Goal – improve organisms and the conditions in which they grow Study and use natural genetic variations Cloning is an example of organismic biotech
23
Organismic Biotech Working with complete, intact organisms or their cells Organisms are not genetically changed with artificial means
24
Prenatal diagnostic screening Newborn screening Carrier screening Confirming disease diagnosis Forensic/identity testing; Genetic testing
25
Cloning Process of producing a new organism from cells or tissues of existing organism. 1997 cloned sheep – “Dolly” in Edinburgh Scotland
26
Cloning
27
Molecular Biotech Changing the genetic make-up of an organism Altering the structure and parts of cells Complex! Uses genetic engineering, molecular mapping and similar processes
28
Genetic testing involves the direct examination of the DNA molecule itself.DNA scans a patient's DNA sample for mutated sequences.
29
Genome Mapping Targeting the specific gene associated with the disease or disorder. Changing the genetic information in a cell Specific trait of one organism may be isolated, cut, and moved into the cell of another organism
30
Gene therapy may be used for treating, or even curing, genetic and acquired diseases like cancer and AIDS by using normal genes to supplement or replace defective genes or to bolster a normal function such as immunity.
32
Biotechnology: Locate & isolate the gene Make changes to the gene Cure the disease
33
Medicine Some new developments delve into the hereditary material of humans known as gene therapy
34
molecular diagnostic devices Diabetes Test Kit Looks for the molecule glucose in your blood – compares its level to ‘normal’
35
Medicine Therapeutant - product used to maintain health or prevent disease Biopharmaceuticals – drug or vaccine developed through biotechnology (Called designer drugs) Biopharming – production of pharmaceuticals in cultured organisms Combination of the agriculture and pharmaceutical industries
36
What combination of molecules will change the chemistry of illness?
37
Organ Regeneration Ethical Issues -- What do you think?
38
Pharmacogenomics is the study of how the genetic inheritance of an individual affects his/her body's response to drugs tailor-made medicines Exact drug dosages Better vaccines
39
Environment Any biotechnological process that may promote a good environment Organisms developed during the gulf war to “eat” oil Organism used in gold mining to “eat” contaminants Problems naturally solved by microorganisms such as bacteria, fungi break down contaminant into a form less harmful or not harmful
40
Oil spillCleaned up by Oil eating microbes Environment
41
Septic sludge Sludge eating microbes Deer Island, Boston State of the art sewage treatment Environment
42
What combination of grains & fruits provide nutrition & good taste?
43
Biotechnology has applications in four major industrial areas: biodegradables
44
Biotechnology has applications in four major industrial areas: environmental uses. 40% less
45
Plant biotech Improve plants and the products produced from them Insect and disease resistance Engineered to have desired characteristics Corn plant produced with high levels of the amino acid Lysine
46
Food and Beverages Use of technology in producing and processing Some biotech principles have been employed for hundreds of years Yeast in baking bread
47
Greater Production Increases yields bST use in cows to produce more milk Higher crop yields from drought, disease & insect resistant crops
48
Food and Bev. Genetically altered crops rBGH milk
49
Efficiency Must keep the cost of improving products as low as possible Biotech results in greater efficiency Inoculating legume seeds with bacteria that allow the plant to pull nitrogen out of the air and put it into the soil Saves the producer the cost of applying N fertilizer
50
Efficiency Results in trees that grow faster and produce wood that is more desirable
51
Health Promoting Foods Food with unique traits Some contain therapeutants Some designed with nutrient enrichment Consumers want foods to provide needed nutrients and in some cases, enhanced foods Do not want side effects from those enhanced foods
