Question

Which one of the following techniques/tools is NOT used for inserting a foreign gene into a cell?

• A. DNA microarray
• B. Electroporation
• C. Gene gun
• D. Microinjection

Hint:

Gene insertion tools physically deliver DNA, while microarrays only measure gene expression.

Answer 1

The Correct Option is A

DNA microarray is used for gene expression analysis, not for gene insertion.
Electroporation, gene gun, and microinjection are all established methods to introduce foreign DNA into cells.
