Recombinant DNA technology (Genetic Engineering) allows genes to be transferred across different

1. species of plants
2. from animals to plants
3. from microorganisms to higher organisms

Select the correct answer using the codes given below.

1. 1 only
2. 2 and 3 only
3. 1 and 3 only
4. 1, 2 and 3

Explanation

All statements are correct

• Recombinant DNA technology (genetic engineering) involves the artificial manipulation and transfer of genes from one organism to another, even across natural species barriers.
• This technology enables the transfer of genes across:
  • Different species of plants: For example, genes from one plant species can be introduced into another to enhance traits like pest resistance or drought tolerance.
  • From animals to plants: Animal genes can be inserted into plants for various purposes, such as creating pharmaceutical-producing plants.
  • From microorganisms to higher organisms: Microbial genes can be introduced into higher organisms to provide new functionalities.
