Question
Explain any two methods of vector less gene transfer.
✓

Answer

The two methods of vectorless gene transfer are:
  1. Micro-injection: The technique of introducing foreign gene in a target cell by injecting the DNA, directly into the nucleus, by micro-needle is called micro-injection.
  2. Electroporation: It is the process in which transient holes are produced in the plasma membrane of the target cell, to incorporate foreign DNA.
