Detailed explanation-1: -Plants, animals or microorganisms that have been changed through genetic engineering are termed genetically modified organisms or GMOs. If genetic material from another species is added to the host, the resulting organism is called transgenic.
Detailed explanation-2: -Genetically modified organisms (GMOs) Gene technology today is an important part of modern biotechnology and is used, among other things, to give bacteria, plants and animals new properties. This is possible by inserting a gene from, for example, a bacterium, into a plant or animal (transgenes).
Detailed explanation-3: -A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.
Detailed explanation-4: -Which describes how DNA is used in biotechnology? The genetic information contained in all living cells can be changed, removed, or added to make products and living organisms function better.
Detailed explanation-5: -Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory.
