Match the organism with its use in biotechnology:
Column I | Column II |
(a) Bacillus thuringiensis | (i) Cloning vector |
(b) Thermus aquaticus | (ii) Construction of first rDNA molecule |
(c) Agrobacterium tumefaciens | (iii) DNA polymerase |
(d) Salmonella typhimurium | (iv) Cry protein |
Select the correct option from the following:
Bacillus thuringiensis has a cry gene that codes for a toxic protein called Cry protein.
Thermus aquaticus is found in hot water spring. It has thermostable DNA polymerase named Taq polymerase.
Agrobacterium tumefaciens has a ti plasmid that is modified to use as cloning vector. The tumor inducing (Ti) plasmid of Agrobacterium tumifaciens has now been modified into a cloning vector which is no more pathogenic to the plants but is still able to use the mechanisms to deliver genes of our interest into a variety of plants.
The construction of the first recombinant DNA emerged from the linking of a gene encoding antibiotic resistance with a native plasmid of Salmonella typhimurium.
