Biotechnology Investigation Wall
Transcript of Biotechnology Investigation Wall
DNA is nucleic acid; genetic material found in the nucleus of a cell.
The complete set of genetic instructions characteristic of an organism, including protein-encoding genes and other DNA sequences.

Ethics & Biotechnology
What is Biotechnology
Biotechnology is the use of living organisms to improve, modify, or produce industrially important products or processes. This is not limited to agriculture; medicine and medical research also use biotechnology.
Parts of Biotechnology
Cloning is another ethical issue associated with biotechnology. Cloning is a process in which a cell, cell product, or organism is copied from an original source. Dolly the Sheep was the first mammal to be cloned. There are many arguments against the use of cloning especially human. The use and cloning of stem cells is strong base to this argument.
Hybrids are not always from biotechnology especially in regards to animals. Hybrids are offspring of two genetically dissimilar parents. An example of a hybrid without the use of biotechnology is a mule; a cross between a donkey and a horse. An example of a hybrid with the use of biotechnology is a pineberry plant, a cross between a pineapple and a strawberry.
Genetic Modification and GMO's.
Genetic modification is simply using biotechnology to change genetic makeup. GMO's or Genetically Modified Organisms, are any organism (plants or animal) that has DNA altered by biotechnology
example: Plants genetically altered to resists pests. In other words, you cannot have GMO's without genetic modification and vise versa.
Types of Biotechnology
There are four types of biotechnology; green, blue, red, and white.
Agriculture and Bioremediation
Agriculture, or the deliberate modification of the Earth's surface through cultivation of plants and raising of animals, is where the majority of where biotechnology is applied. Another form of environmental biotechnology is by use in bioremediation, or the use of microorganisms to degrade toxic compounds.
Red biotechnology is applied to medical processes. Some examples are the designing of organisms to produce antibiotics, and the engineering of genetic cures through genetic manipulation.
White biotechnology, also known as industrial biotechnology, is biotechnology applied to industrial processes. An example is the designing of an organism to produce a useful chemical. Another example is the using of enzymes as industrial catalysts to either produce valuable chemicals or destroy hazardous/polluting chemicals such as oil eating bacteria for oil spills.
Green biotechnology is biotechnology applied to agricultural processes. Another example is the designing of transgenic plants to grow under specific environments in the presence (or absence) of chemicals. One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture. An example of this is the engineering of a plant to express a pesticide, thereby ending the need of external application of pesticides.
Blue biotechnology is a term that has been used to describe the marine and aquatic applications of biotechnology, but its use is relatively rare.
There are many people that believe that GMO's should be labeled and that they are unhealthy. Ethically (ethics is a set of principles relating to what is morally right or wrong) what do you think?
There is little doubt that biotechnology is part of the future of the world. All facets have positive and negative repercussions, but it is our jobs to determine which of these is worth the risk.
