Question

Match the organism with its use in biotechnology.

(a)	Bacillus thuringiensis	(i)	Host cell for human insulin production
(b)	Thermus aquaticus	(ii)	Taq polymerase
(c)	Agrobacterium tumefaciens	(iii)	Insecticidal protein coding gene
(d)	E. coli	(iv)	Ti plasmid

Select the correct option from the following.

• A. (a) (b) (c) (d)
  (iii) (ii) (iv) (i)
• B. (a) (b) (c) (d)
  (iii) (ii) (i) (iv)
• C. (a) (b) (c) (d)
  (ii) (iii) (i) (iv)
• D. (a) (b) (c) (d)
  (i) (ii) (iii) (iv)

Answer 1

The correct option is A (a) (b) (c) (d)

(iii) (ii) (iv) (i)
cry gene codes for insecticidal protein.
Taq polymerase is obtained from Thermus aquaticus.
The Ti plasmid of Agrobacterium tumefaciens has now been modified into a cloning vector to deliver genes into a variety of plants. E. coli is used as host cell for human insulin production.
