If you transform a cell with an alien piece of DNA only, What is the possibility?

1.      This alien piece becomes a part of the host genome.

2.      It doesn't become a part of the host's genome but keeps on replicating

3.      The cloning of genes won't get affected in the absence of Origin of replication.

4.     Multiple identical copies of an alien piece of DNA can be formed irrespective of its integration into the host's genome.
