Cre ("causes recombination" is able to recombine specific sequences of DNA without the need for cofactors. The enzyme recognizes 34 base pair DNA sequences called loxP (“locus of crossover in phage P1”)
cre is a recombinase that can specificly recombine a short sequences called the Lox sequences. This is the well-kown cre-loxp system for gene knockout.
