Plasmid Architecture and Vector

Plasmids are made up of circular double chains of DNA. The circular structure of plasmids is made possible by the two ends of the double strands being joined by covalent bonds. Although a good number of plasmids have a covalently closed circular structure, some plasmids have a linear structure and do not form a circular shape.

Types:

1. Resistance Plasmids
2. Degradative Plasmids
3. Fertility Plasmids
4. Col Plasmids
5. Virulence Plasmids

Vector: A vector refers to any piece of molecule that contains genetic material that can be replicated and expressed when transferred into another cell.
