SUB-CATEGORIES OF BIOTECHNOLOGY:\n\nRED BIOTECHNOLOGY is biotechnology applied to medical processes. Some examples are the designing of organisms to produce antibiotics, and the engineering of genetic cures to cure diseases through genomic manipulation.\n\nWHITE BIOTECHNOLOGY, also known as GREY BIOTECHNOLOGY, is biotechnology applied to industrial processes. An example is the designing of an organism to produce a useful chemical. White biotechnology tends to consume less in resources than traditional processes when used to produce industrial goods.\n\nGREEN BIOTECHNOLOGY is biotechnology applied to agricultural processes. An example is the designing of an organism to grow under specific environmental conditions or in the presence (or absence) of certain agricultural 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 eliminating the need for external application of pesticides. Whether or not green biotechnology products such as this are ultimately more environmentally friendly is a topic of considerable debate.\n\nBIOINFORMATICS is an interdisciplinary field which addresses biological problems using computational techniques. The field is also often referred to as computational biology. It plays a key role in various areas like functional genomics, structural genomics, and proteomics amongst others, and forms a key component in biotechnology and pharmaceutical sector.\n\nThe term BLUE BIOTECHNOLOGY has also been used to describe the marine and aquatic applications of biotechnology, but its use is relatively rare.

Biotechnology is a technology based on biology, especially when used in agriculture, food science, and medicine.\n\nOf the many different definitions available, the one formulated by the UN Convention on Biological Diversity is one of the broadest:\n\n"Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use." (Article 2. Use of Terms) \nBiotechnology can also be defined as the manipulation of organisms to do practical things and to provide useful products.\n\nOne section of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer, milk products, and skin). Naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and produce biological weapons.

You are talking aboujt a thesis here. This sounds like a school asignment so i suggest you go and do your own reseacrh.\n\nTrangeneics is a relatively new field that has taken off in recent years. You are manipulating the genome to creat specific actions. For example, in a mouse you can insert a gene that codes for  a particular brain receptor. You would isolate this gene, and use a plasmid vector and insert it into the mous eline and you now have the gene in a mouse. These are called engineered or transgenic mice. You can also do what is called a knockout, where you remove a aprticular gene to test an effect.\n\nThere is a TON of info in scientific journals, online and in texts. Do some background. For a specific question or to clarify I will gladly help, but Yahoo answers is NOT where you go to get your homework done.

Biotechnology or BT is industrial application of biology. Its biology in the service of mankind. It involves application of plants, animals and microorganisms in industry. On the other hand, Biomedical engineering uses traditional engineering expertise to solve problems in biology and medicine. Hearing aids,pacemakers etc. are the gifts of biomedical engineering to mankind.\n\nUnder-grad courses in BT - \nYou can go either for BSc. Biotechnology, B.E Biotech or B.Tech Biotech, B.E Biomedical engineering etc. For list of Biotechnology colleges and Biomedical engineering colleges, visit http://www.biotechworld.cjb.cc\n\nPost-grad courses in BT - \nMSc. in Biotechnology has good career prospects. Biotech is a booming sector and the growth oppurtunities are high. The Biotech sector includes - Biopharma, Biotech, Biotech services, Bioindustrial, Bioinformatics etc. After BSc., those who want to go for research, choose MSc. and then go for Phd. On the other hand, some go for MBA-Biotechnology. Career oppurtunities for both these courses are good.\n\nAfter doing MSc. Biotech, one can join R&D dept. of any good Biotech company. US is the best destination for Biotechnology. It stands out in the field of research as well as the biotech market is much developed in the US. Similar, is the case with UK, Canada and a few EU countries. Coming to India and China, these countries are really trying hard. Australia is good study destination as well for BT studies in Asia-Pacific region.\n\nFor details on entrance exams and admission procedures as well as more career options in BT, you may visit -\nhttp://www.biotechworld.cjb.cc\n\nThe other career prospect is MBA-Biotechnology. MBA-Biotech has bright prospects. It is a 2-year programme in management. Only science stream graduates/ those in their final year of graduation can only apply for this course. This course gives equal emphasis to both Biotechnology and management. In India, University of Pune(PUMBA), Amity Institute at Noida are the preferred institutes for this course.

Biotechnology has different meanings to different people. Some define biotechnology as the use and exploitation of microorganisms to produce products of industrial or commercial interest like beer brewing, cheese making, and production of sour milk. But is this the right definition for biotechnology?\n The answer is no, this is a narrow definition that can't describe biotechnology. the exploitation of genetically engineered microorganisms, centered on the technology of genetic engineering or recombinant DNA, constants modern biotechnology. So, in the light of the previous sentence, biotechnology is defined as the application of scientific and engineering principles to the processing of materials by biological agents to provide goods and services. Working on a food material...\n\nA Biotechnologist doing what she knows best in the lab.\n\n\nIf we look at modern biotechnology that is based on the DNA technology of recombinant, and its different usages, then we could classify the biotechnology in the different fields such as: medical biotechnology, ecological biotechnology, bioprocess, biotechnology navy, pharmaceutical and industrial biotechnology and farming biotechnology.\n\nBiotechnology seems to take the sudden biological new revolution. Its importance comes from that it brought us by a world of " organized" the products that are based in the natural world to the place of on the chemical and industrial procedures.\n\nTo summarize, biotechnology is considered as the science of the future that will attract  interest of many people and will bring about a big revolution in\nthe lives of the people and will show human how to live a even more comfortable life with less stress.

a genus of gram negative bacteria that are carried as parasites by ticks and fleas among other organisms they cause many diseases one example is typhus.they are obligate parasites thus they cannot live without their host, choosing only specific organisms as hosts.

I have been farming organically for five years now, I am committed to doing it the natural way. It means that everything you do you do it without chemicals. For example, mixing ground up Jalapenos with a tad of Bacon grease and a little well water is a far better pesticide than malethon, bugs hate it and they never get immune to it. I don't farm commercially but I betcha that most of what goes for organic is not.

Bacteriocins are toxins that are produced by bacteria to kill  similar types of bacteria. Just as there is competition between different species of bacteria, there is also competition between different strains of the same species. They have similar mechanisms to most antibiotics. Many types of bacteria produce bacteriocins including Baccilli, Enteric bacteria (e.g. E.coli), and most gram-positives.
