b. Thermus aquatics
c. Aquabacterium tumefaciens
d. Salmonella typhimurium
Column-II
i. Cloning vector
ii. Construction of first rDNA
iii. DNA polymerase
iv. Cry proteins
2. a(iv) b(iii) c(i) d(ii)
Solution:
a. Bacillus thuringiensis - Cry proteins (insecticidal protein crystal)
b. Thermus aquatics - DNA polymerase (For thermal stability)
c. Aquabacterium tumefaciens - Cloning vector (Agrobacterium tumefaciens cell contains a plasmid known as the Ti (tumor-inducing) plasmid)
d. Salmonella typhimurium - Construction of first rDNA (constructed by Stanley Cohen and Herbert Boyer in 1972)
