Detailed explanation-1: -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-2: -Definition. Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.
Detailed explanation-3: -Genetic modification Often GM involves isolating and removing the DNA encoding a single gene from one organism, manipulating it outside the cell (in a laboratory) and reinserting it into the same organism or into the genetic material of another organism.
Detailed explanation-4: -Genetic engineering is also called genetic modification or GM. It involves modifying the genome of an organism by identifying and removing a gene from the genome of one organism, and introducing it into the genome of another organism to result in a desired characteristic.
Detailed explanation-5: -Genetic engineering is the modification of an organism’s phenotype by manipulating its genetic material. Some genetic engineering uses the principle of recombination.
