Detailed explanation-1: -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. For example, genetic engineering may involve adding a gene from one species to an organism from a different species to produce a desired trait.
Detailed explanation-2: -Gene Transfer: The introduction of new DNA into an existing organism’s cell, usually by vectors such as plasmids and modified viruses. Cells may be modified ex vivo for subsequent administration to humans, or may be altered in vivo by gene therapy given directly to the subject.
Detailed explanation-3: -Transposons ("jumping genes") are small pieces of DNA that encode enzymes that enable the transposon to move from one DNA location to another, either on the same molecule of DNA or on a different molecule.
