Match List I with List II : List I List II A. Genetically modified organism I. Agrobacterium tumefaciens B. Thermostable DNA polymerase II. Bt cotton C. Ti plasmid III. Thermus aquaticus D. pBR322 IV. Escherichia coli Choose the correct answer from the options given below :
A. A-II, B-III, C-I, D-IV
Bt cotton is a genetically modified organism created by inserting the cry gene from Bacillus thuringiensis into cotton. Thermostable DNA polymerase, such as Taq polymerase used in PCR, is isolated from the thermophilic bacterium Thermus aquaticus. Ti plasmid (Tumor-inducing plasmid) is naturally found in Agrobacterium tumefaciens, which is used as a cloning vector for plants. pBR322 is a widely used artificial plasmid cloning vector in Escherichia coli. Therefore, the correct matching is A-II, B-III, C-I, D-IV. Answer: A-II, B-III, C-I, D-IV
