Definition: The word "biotechnology" refers to a field that utilizes living organisms, including bacteria, cells, and genetic material, to produce new products. It's an interdisciplinary discipline that involves research, development, manufacturing, and marketing of biologic, chemical, physical, or biological technologies. Defining "biotechnet," we could say it's the process by which organisms are modified for desired purposes. This can be achieved through various approaches such as cloning, genetic modification, gene therapy, or even modifying living cells to produce new drugs or medical treatments. An example of this is the development of cancer treatments using genetically modified cells that contain a specific gene. These cells not only fight against the disease but also help in the prevention and detection process. Another example is bioremediation, which uses living organisms (like bacteria) to clean up polluted environments like rivers or oceans by converting pollutants into harmless ones.
