Cre-Lox recombination. Molecular model of the enzyme CRE (cyclization recombination) recombinase (purple) mediating the recombination of strands of DNA (deoxyribonucleic acid,pink and green). It is doing this at a specific target sequence,called the Lox sequence,found in the bacteriophage P1. Cre-Lox recombination is used in genetically modified organisms to allow researchers to control gene expression and delete or insert DNA sequences | |
