Q: Recombination DNA technology (Genetic Engineering) allows genes to be transferred
across different species of plants
from animals to plants
from microorganisms to higher organisms
Select the correct answer using the codes given below.
a) 1 only b) 2 and 3 only c) 1 and 3 only d) 1, 2 and 3
Correct Answer: Option (d)
Recombinant DNA is the general name for taking a piece of one DNA and combining it with another strand of DNA. All three options in the question are correct. Examples of these methods are: –
1) The gene ‘Chitinase’ has source organism ‘Rice’ and characteristic conferred on transformed plants is Fungal resistance.
2)The gene ‘2’-5′ oligoadenylate synthetase’ has source organism ‘Rat’ and characteristic conferred on transformed plants is Virus resistance.
3)Human Proteins ‘Somatostatin’ has been synthesized from genes in bacteria and used in the treatment of Growth disorders.
Hence, option (d) is correct.
