concept and importance of biotechnology

Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Steps involved in the engineering of a recombinant DNA molecule. Some products are intended to mimic the human counterpart, whereas others are intended to differ from the human counterpart and may be analogues, chemically modified (e.g., pegylated) or novel products (e.g., single chain or fragment antibody products, gene transfer vectors, tissue-engineered products). What is the reserve food material in red algae? Approximately 6,000 years ago, humans began to tap the biological processes of microorganisms in order to make bread, alcoholic beverages, and cheese and to preserve dairy products. Applications of Recombinant DNA Technology: 3 Applications, Applications of Biotechnology in Industry and Healthcare, Tools and Techniques Used for Plant Tissue Culture. The practice of quarantining to prevent the spread of disease was in place long before the origins of disease were known. Our editors will review what you’ve submitted and determine whether to revise the article. A fledgling “biotech” industry began to coalesce in the mid- to late 1970s. What are the general characters of bryophytes? Different areas of medicine in which biotechnology is used to develop diagnostic kits and cure are presented in the Figure 22.1. The development of new technologies have resulted into production of large amount of biochemically-defined proteins of medical significance and created an enormous potential for pharmaceutical industries. Crop improvement, by selecting seeds from the most successful or healthiest plants, to obtain a new crop having the most desirable traits, is a form of early crop technology. Fermentation is perhaps the most ancient biotechnological discovery. Today, biotechnology researchers seek to discover the root molecular causes of disease and to intervene precisely at that level. Agricultural applications of biotechnology have proved the most controversial. Farmers learned that using only the seeds from the best plants would eventually enhance and strengthen the desired traits in subsequent crops. Apart from these, there are many other biotechnological treatments applied to monito… The expressed protein or gene may have the identical amino acid or nucleotide sequence as the human endogenous form, or may be intentionally different in sequence to confer some technical advantage such as an optimized pharmacokinetic or pharmacodynamics profile. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. In world, USA, Japan, and many countries of Europe are leaders in biotechnological researchers encouraged by industrialists. Studies by the United Nations, the U.S. National Academy of Sciences, the European Union, the American Medical Association, U.S. regulatory agencies, and other organizations have found GMO foods to be safe, but skeptics contend that it is still too early to judge the long-term health and ecological effects of such crops. Microorganisms can be used to enhance to recovery of metals from low-grade ores and from effluents containing undesirable quantities of heavy metals or other toxins. Synthetic insulin and synthetic growth hormone and diagnostic tests to detect various diseases are just some examples of how biotechnology is impacting medicine. With the help of modern biotechnology, many diagnostic tools have been introduced for the detection of diseases in a quick and accurate manner. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. (h) Large-scale production of fructose from inexpensive forms of glucose. unearthed in 1881 and explaining the preparation of beer. In the late 20th and early 21st centuries, the land area planted in genetically modified crops increased dramatically, from 1.7 million hectares (4.2 million acres) in 1996 to 160 million hectares (395 million acres) by 2011. (n) Production of diagnostic kits for toxoplasmosis identification. The most prominent approach used is genetic engineering, which enables scientists to tailor an organism’s DNA at will. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. The terms Grey and White Biotechnology have been coined for the application of biotechnological processes in environmental and industrial production contexts. In addition to the tools mentioned above, biotechnology also involves merging biological information with computer technology (bioinformatics), exploring the use of microscopic equipment that can enter the human body (nanotechnology), and possibly applying techniques of stem cell research and cloning to replace dead or defective cells and tissues (regenerative medicine). Content Guidelines 2. In 1897 the discovery that enzymes from yeast can convert sugar to alcohol lead to industrial processes for chemicals such as butanol, acetone and glycerol. This article was most recently revised and updated by,, National Center for Biotechnology Information - PubMed Central - Future Applications of Biotechnology to the Energy Industry, biotechnology and bioengineering advance science and medicine - Student Encyclopedia (Ages 11 and up). This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Biotechnology is also involved in controlling the environmental pollution through biodegradation of potential pollutants, recycling of wastes and other waste treatment technologies. Biotechnology is also known as biological technology. Do eukaryotic cells have restriction endonucleases? In 2002, antibodies were (along with vaccines) the most important therapeutic class of drugs under development and there are also more recent market studies more than 100 antibodies or antibody fragments were at the clinical development stage in 2002 and research and development is being carried out on around 470 more in about 200 companies around the world (Table 22.6,7). The traditional pesticide market, on the other hand has been stagnating for years. …again making tentative overtures to biotechnology, although a relationship has existed at least since Mary Shelley’s, The intersection of nanotechnology and biotechnology offers the possibility of achieving new functions and properties with nanostructured surfaces. As mentioned above, recombinant human insulin was the first recombinant medicine in the world, produced by Genentech and brought to market in 1982.
