Question

Which of the following methods of transferring DNA is useful in bacteria and plants, but not in animals?

विकल्प

• Bacteriophage infection

• Plasmid transfer

• Microinjection of DNA

• Laser irradiation of cells in a fluid containing DNA

Answer 1

Plasmid transfer

Explanation:

This method of transferring DNA is useful in bacteria and plants because plasmids can naturally transfer genetic material in these organisms. However, plasmid transfer is not commonly used or effective in animals. Bacteriophage infection is mainly bacterial, microinjection of DNA and laser irradiation are useful in animals, unlike plasmid transfer. Therefore, plasmid transfer is the DNA transfer method useful in bacteria and plants, but not in animals.
