Transgenic Organism

A transgenic organism is a genetically engineered organism. They are created by firstly isolating the DNA and then fragmenting it using restriction enzymes before recombining the DNA in a new controlled way. The restriction enzymes cleave the DNA at a specific restriction site and mainly create sticky ends that have complementary sequences to each other and can therefore adhere together. 

The recombined DNA is reintroduced to a cell or organism. The main use of this technology is for experimental studies, however a very importatant aspect of the application is developing and improving varities of crop plants and domesticated animals .
