The key difference between transgenic and knockout mice is that transgenic mice have foreign genes inserted into its genome while knockout mice have a functionally inactivated gene of interest. Genetic engineering is the field of genetics in which the genetic makeup of an organism is modified or manipulated by recombinant dna technology.
A transgenic animal is where you take a piece of dna that's not normally found in that animal and place it back among its normal chromosomes. So for example, you can make a transgenic by having a piece of dna that you clone in a laboratory and inject it into a fertilized egg of a mouse embryo, for example, then that becomes integrated into the chromosome.
A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. Transgenesis is the process by which mixing up of genes takes place.
