Question

______A_______ is a transformation method more suitable for animals while ______B_______ is more suitable for plants.

• A. A - Microinjection, B - gene gun
• B. A - Gene gun, B - microinjection
• C. A - Biolistics, B - gene gun
• D. A - Biolistics, B - microinjection

Answer 1

The correct option is A A - Microinjection, B - gene gun

The process by which exogenous DNA is transferred into host cells is termed as transformation. This brings about a genetic alteration in the cell. Microinjection and biolistics are methods of gene delivery into host cells.

• Microinjection - In this method, the recombinant DNA is directly injected into the nucleus of the cell. It is more suitable for animal cells.

• Biolistics - In this method, cells are bombarded with high velocity micro-particles of gold or tungsten coated with DNA. It is also known as a gene gun and is more suitable for plant cells.
