Final answer:
The Cre recombinase enzyme recognizes a specific DNA sequence known as the loxP site. It catalyzes recombination between paired loxP sites.
Step-by-step explanation:
The Cre recombinase enzyme recognizes a specific DNA sequence known as the loxP site. The loxP site consists of two 13 bp inverted repeats with an 8 bp spacer region in between. Cre recombinase binds to these loxP sites and catalyzes recombination, allowing for the excision, insertion, or inversion of DNA segments between the paired loxP sites.
