If you transfom a cell with an alien piece of DNA only, What is the possibility?
1. This alien piece becomes a part of host genome.
2. It doesn't become a part of host's genome but keeps on replicating
3. The cloning of gene won't get affected in the absence of Origin of replication.
4. Multiple identical copies of alien piece of DNA can be formed irrespective of its integration into host's genome.
