Solution

Griffith factor is a particular material that could be picked up by a living cell from the dead remains of its relatives and develop the property of the same. The phenomenon is called transformation. It is now widely used in biotechnology.
The work of Avery et al proved that Griffith factor of DNA or gene. They found DNA to be molecular basis of heredity.
Both the discoveries indicated that DNA could be extracted from cell and passed into another cell. Today gene transfer is being carried out in preparation of genetically modified organisms, replacement of defective genes (gene therapy) and production of important biochemicals.
