In the presence of a restriction
             enzyme, the plasmid DNA was 'cut' to

             fo f f rm a complementary sequence. Then, a
             DNA       fr f f agment  (green    fl f f uorescent
             protein ggene) frff om the jellyfiff sh was 'cut'

             with a restriction enzyme to foff rm a
             sequence. These DNA frff agments give an
             organism the characteristic of being able

             to glow in the dark. They joined both the
             plasmids and DNA frff agments together

             using a centrifuff gation method. This
