|---|---|
| Origin of replication (ori) | Where replication starts; controls copy number |
| Selectable marker | Identifies & eliminates non-transformants; usually antibiotic-resistance genes (amp, tet, kan, chloramphenicol) |
| Cloning sites | Preferably a single recognition site per restriction enzyme to link alien DNA |
