plasmid in biotechnology#explanation # biology notes

A plasmid is a small, circular DNA molecule found mainly in bacteria. It can replicate independently of the bacterial chromosome and is widely used as a vector in biotechnology to transfer genes from one organism to another.
Functions of Plasmids in Biotechnology
Carry and transfer desired genes into host cells.
Help in gene cloning and genetic engineering.
Enable production of recombinant proteins.
Serve as tools for studying gene expression and function.
Applications
Production of human insulin, growth hormone, and vaccines.
Development of genetically modified organisms (GMOs).
Gene therapy research.
Manufacturing industrial enzymes and biopharmaceuticals.
Molecular biology and DNA research.
Conclusion:
Plasmids are important biotechnology tools that act as gene carriers, helping scientists produce useful medicines, improve crops, and advance genetic research.
