Question

In which of the following method, foreign DNA is directly injected into a cell?

• A. Direct gene transfer
• B. Liposome-mediated gene transfer
• C. Microinjection
• D. All of the above

Answer 1

The correct option is C Microinjection

• Direct gene transfer includes the transfer of the foreign gene of interest into the host plant cell without the help of a vector.
• Liposome-mediated gene transfer includes the transfer of foreign DNA with the help of liposomes. Liposomes are spheres of lipids that can be used to transport molecules into the cells.
• Microinjection includes direct injection of DNA is into plant protoplasts or cells using a fine-tipped glass needle or micropipette.

Thus, the correct answer is option C.
