How is bacterial transformation useful?
Bacterial transformation is a process where horizontal transfer of exogenous genetic material may be introduced into a bacterial cell.
Applications of bacterial transformation are :
1) to make multiple copies of DNA called DNA cloning.
2) to make large amounts of specific human proteins , for example human insulin, which can be used to treat people with Type 1 diabetes.
3) to genetically modify a bacterium or other cell.
Bacteria are commonly used as host cells for making copies of DNA in the lab because they are easy to grow in large numbers . Their cellular machinery naturally carries out DNA replication and protein synthesis.
