→ Plasmid is an extra small circular DNA present in the bacterium cell which is different from other DNA.
→ Plasmid is able to replicate independent of the chromosomal DNA in the cell.
→ It contains genes which can produce specific type of chemicals.
→ Plasmid can be extracted from the cell.
→ The specific sequence of plasmid can be cut by using restricted endonucleases and at that place desirable gene can be introduced by ligase enzyme.
→ Plasmid plays significant role in recombinant DNA Technology.
