Question

Microinjection and gene gun methods are the part of:

• A. Direct gene transfer
• B. Indirect gene transfer
• C. PCR technique
• D. DNA test

Answer 1

The correct option is A Direct gene transfer

To directly introduce alien DNA into host cells, there are several ways. Two of them are microinjection and gene gun method.

• Microinjection is the introduction of foreign genes into plant or animal cells using micropipettes or glass needles.

• Particle gun/gene gun/biolistic method is a technique in which tungsten or gold particles coated with foreign DNA are bombarded into target cells to facilitate entry of the foreign genes.

So, microinjection and gene gun methods are the part of direct gene transfer.
