<<–2/”>a >a href=”https://exam.pscnotes.com/biotechnology/”>Biotechnology is defined as the industrial application of living organisms and their biological processes such as biochemistry, Microbiology, and Genetic engineering, in order to make best use of the Microorganisms for the benefit of mankind. Modern biotechnology provides breakthrough products and technologies to combat debilitating and rare diseases, reduce our environmental footprint, feed the hungry, use less and cleaner energy, and have safer, cleaner and more efficient industrial manufacturing processes.
Biotechnology began in the 1970s after the development of genetic engineering that allowed scientists to modify the genetic material of living cells. Genetic engineering is the manipulation of DNA Molecules to produce modified Plants, animals, or other organisms. DNA is the part of a cell that controls the genetic information of an animal or plant. DNA is a double-stranded molecule that is present in every cell of an organism. The genetic information is contained in individual units or sections of DNA called genes. The genes that are passed from parent to offspring determine the traits that the offspring will have.
Applications of Biotechnology
- Health and medicine
Fighting infectious diseases : Biotechnology is used extensively in the study of infectious diseases such as SARS (Severe Acute Respiratory Syndrome), and influenza. As a result more effective pharmaceuticals have been developed.
Development of Vaccines and antibiotics : Using technology, microorganisms are used to develop antibiotics and vaccines to cure diseases. For example, bacteria Bacillus polymysea is used to produce polymyxin B (antibiotic used to cure urinary tract infections), fungus Penicillium notatum is used to produce penicillin (used to cure pneumonia, and many other bacterial infections.)
Treating genetic disorders : Disease can occur when genes become defective due to mutations. With advancements in biotechnology, in the near future it will be possible to use gene therapy to replace an abnormal or faulty gene with a normal copy of the same gene. It may be used to treat ailments such as heart disease, inherited diseases such as SCID, and Thalassaemia.
In forensic science : A lot of New techniques have been developed such as DNA fingerprinting, besides having a number of other applications which have facilitated the speedy identification of the criminals.
Cleaning up and managing the environment : Cleaning up the environment using living organisms is called bioremediation. Naturally occurring, as well as genetically modified microorganisms, such as bacteria, Fungi and ENZYMES are used to break down toxic and hazardous substances present in the environment.
Biotechnology has also made possible the production of crops improved disease resistan; herbicide-toleran and insecticide-resistan. Plants with improved nutritional value for Livestock have also been obtained through biotechnology.
Control of pests : One application of biotechnology is in the control of insect pests. The genetic make-up of the pest is changed by causing some mutations. These pests become sterile and do not reproduce further.
Manufacturing and bio-processing : With the help of new biological techniques it has become possible to grow, the plants that produce compounds for use in detergents, paints, lubricants and plastics on large scale.
Food and drinks : Biotechnology, has also made the processing of foods and their products easier. Preservation and storing of food for consumption later has become easy and cheap with the help of biotechnology. Seedless grapes and seedless citrus fruits have been developed using biotechnology.
Biotechnology has been used in the industry to produce new products for human consumption. Food additives have been developed which help in the preservation of food. Microorganisms are used in the mass production of items such as cheese, yoghurt, and alcohol.
Biotechnology through Genetic engineering has made Food Crops more resistant to disease, but the mere act of modification of the naturally selected food crops may actually disturb the delicate balance of Biodiversity-2/”>Biodiversity which exists in nature causing a disturbance to the natural balance.
The production of GMOs has negative impacts on the natural ecosystem which are not apparent now but will be apparent in the future. For example, genetic changes in a particular plant or animal might render it harmful to another organism higher up in the food chain and ultimately this effect may build up to destroy the entire food chain in which that plant plays a role.
GMOs have been known to retain some of the genetically modified DNA in the final product made for human consumption. Such remnants of genetic material are harful to human health and can cause production of previously unknown allergens.
Genetically modified plants and animals have the potential to replace traditional farming or say Poultry and meat-producing practices. This will result in destruction of economies based on these products.
In the context of applications of genetic engineering in human life, misuse of this technology in the production of biological warfare or weapons is a very major disadvantage.
Genetic engineering is being used to create human organs but in the long run if it can create genetically modified, perfect human specimens who are better than the creators than this may be disastrous.
Nature selection in man and the resulting diversity of the human genetic pool is essential for the survival of the species. Genetic engineering will interfere with this process too causing unknown complications.,
Biotechnology is the application of biological processes and organisms to industrial and other purposes. It is a rapidly growing field with a wide range of applications, from agriculture to medicine.
One of the most common applications of biotechnology is genetic engineering. Genetic engineering is the process of modifying an organism’s DNA. This can be done for a variety of purposes, such as improving crop yields, developing new drugs, or creating biofuels.
Gene therapy is another important application of biotechnology. Gene therapy is the process of using genetic engineering to treat or prevent disease. This can be done by inserting a healthy gene into a person’s cells to replace a defective gene, or by using gene editing to correct a genetic mutation.
Cloning is another area of biotechnology that has generated a great deal of controversy. Cloning is the process of creating an identical copy of an organism. This can be done using somatic cell nuclear transfer, which involves removing the nucleus from a somatic cell (a cell from the body) and inserting it into an egg cell that has had its nucleus removed. The resulting embryo is then implanted into a woman’s uterus and allowed to develop into a baby.
Stem Cell Research is another area of biotechnology that is still in its early stages. Stem cells are cells that have the ability to develop into any type of cell in the body. This makes them a potential source of new Tissues and organs for transplantation. However, stem cell research is also controversial, as it involves the destruction of human embryos.
Bioethics is the study of the moral and ethical issues raised by biotechnology. Some of the key ethical issues in biotechnology include the use of human embryos in research, the potential for genetic discrimination, and the safety of genetically modified organisms.
Intellectual Property Rights (IPRs) are legal rights that protect the intellectual property of inventors, creators, and other innovators. IPRs include patents, copyrights, trademarks, and trade secrets. Patents protect inventions, copyrights protect creative works, trademarks protect brand names and logos, and trade secrets protect confidential information.
IPRs play an important role in the development and commercialization of new technologies. They provide inventors and creators with the incentive to invest in research and development, and they help to ensure that the fruits of their labor are rewarded.
However, IPRs can also raise ethical concerns. For example, some people argue that patents on life forms are morally wrong, as they give corporations control over living things. Others argue that copyrights on creative works can stifle innovation, as they prevent others from building on the work of others.
Biosafety is the practice of preventing the accidental release of genetically modified organisms into the environment. Biosecurity is the practice of preventing the intentional release of genetically modified organisms into the environment for malicious purposes.
Both biosafety and biosecurity are important considerations in the development and use of genetically modified organisms. Genetically modified organisms can potentially harm the environment if they are released into the wild. They can also be used as bioweapons, which are weapons that use biological agents to harm people or animals.
Regulation of biotechnology is the process of ensuring that the development and use of biotechnology is safe and ethical. This is done through a variety of laws and regulations, which vary from country to country.
Public perception of biotechnology is the way that the general public views biotechnology. Public perception is important, as it can affect the development and use of biotechnology. If the public is opposed to biotechnology, it may be difficult to get new technologies approved or to commercialize them.
The future of biotechnology is uncertain. However, it is likely that biotechnology will continue to play an increasingly important role in our lives. Biotechnology has the potential to solve some of the world’s most pressing problems, such as hunger, disease, and Environmental Degradation. However, it also has the potential to create new problems, such as genetic discrimination and the accidental release of genetically modified organisms into the environment. It is important to carefully consider the ethical and social implications of biotechnology as we move forward into the future.
