1. Bam HI cuts at positions: 3, 50, 63, 8
Hin dIII cuts at positions: 32, 42, 28, 29
Eco RI cuts at positions: 19, 28, 45, 18, 20
2. Fragment counts and lengths:
- Bam HI: 3 cuts → 4 fragments; longest fragment length: 9
- Hin dIII: 4 cuts → 5 fragments; longest fragment length: 32
- Eco RI: 4 cuts → 5 fragments; longest fragment length: 20
3. Banding patterns on gel (from top to bottom, largest to smallest):
- Lane 1 (Bam HI): bands at 9, 8, 63, 50
- Lane 2 (Hin dIII): bands at 32, 29, 28, 42
- Lane 3 (Eco RI): bands at 20, 19, 18, 45, 28
