Bio-engineered organisms are living beings that have been modified using techniques from genetic engineering. This process involves altering the DNA of an organism to enhance certain traits or introduce new characteristics. These modifications can be applied to plants, animals, and microorganisms, leading to benefits such as increased crop yields or improved disease resistance. One common example of bio-engineered organisms is genetically modified crops, which are designed to withstand pests and harsh environmental conditions. Additionally, bio-engineered bacteria are used in various applications, including the production of insulin and other pharmaceuticals, showcasing the potential of these organisms in medicine and agriculture.
