Detailed explanation-1: -Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means. Transgenic organisms are generated in the laboratory for research purposes.
Detailed explanation-2: -A transgenic animal is one whose genome has been altered by the transfer of a gene or genes from another species or breed.
Detailed explanation-3: -Transgenic organisms contain foreign DNA that has been introduced using biotechnology. Foreign DNA (the transgene) is defined here as DNA from another species, or else recombinant DNA from the same species that has been manipulated in the laboratory then reintroduced.
Detailed explanation-4: -A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques.
Detailed explanation-5: -Transgenics refers to the transfer of genes from one organism to another which, in the context of aging, means transferring into a model organism a gene that extends longevity in another organism.
