A technique in transgenic animals in which the desired gene is inserted into the eggs of the animal is called:
Correct answer: B. Microinjection
- A. Embryonic Stem Cell mediated Transfer
- B. Microinjection
- C. Retro-virus mediated gene Transfer
- D. Virus vectors
Explanation
Microinjection: This option is the correct answer. Microinjection is a technique commonly used in transgenic animal research. In this technique, a desired gene is directly injected into the pronucleus of a fertilized egg or the nucleus of a developing embryo. The injected gene becomes incorporated into the genome of the animal, leading to the expression of the desired gene in its offspring.
