4. Insert the following action script on the first keyframe:
for (i=2; i<30; i=i+1)

{

Duplicatemovieclip ("/dna1", "DNA" Add (i), i);

SetProperty ("/dna" Add I, _rotation, GetProperty ("/dna")
Add (i-1), _rotation) +11);

SetProperty ("/dna" Add I, _x, GetProperty ("/dna")
Add (i-1), _x) +10);

}

SetProperty ("/dna1", _visible, "0");

5. On the second keyframe, insert the following action:

for (i=2 i < i = i+1)

{SetProperty ("/dna" Add I, _rotation, GetProperty ("/dna")
Add I, _rotation) + 5);

}

6. On the third keyframe, insert the following action:

gotoAndPlay (2);
