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

Answer:

(d)

Explanation

Recombinant DNA is the general name for taking a piece of one DNA, andand 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’ have been synthesized from genes in bacteria and used in the treatment of Growth disordersTikdam: genes can be transferred from any organism to any other organism so all are correct
