- It contains small amount of genes.
- Certain parts of the plasmid can be cut by restriction enzymes.
- Some plasmids synthesize specific chemicals. Such as Colicin, Vibrin.
- Number of plasmids is 1-1000 per cell.
- Replication of plasmids can occur in a semiconservative process.
- They can move from one bacterial cell to another.
