Question

At what developmental stage are genetic transformation techniques typically applied in animals?

पर्याय

• Adult somatic cells only

• Fertilized eggs or early-stage embryos

• Differentiated tissue cells

• Post-natal development stage

Answer 1

Genetic transformation techniques in animals specifically target fertilized eggs or early-stage embryos. This developmental stage is critical because it allows the foreign DNA to be integrated into the genome before extensive cell differentiation occurs, ensuring the transformed genes are present in all cells of the organism.
