Step-by-step solution

Thermus aquaticus is the source of the thermostable DNA polymerase (Taq polymerase) used in PCR. Agrobacterium tumefaciens contains the Ti plasmid, which is modified and used as a cloning vector to deliver genes of interest into dicot plants. Bacillus thuringiensis produces insecticidal Cry proteins that are toxic to certain insect pests. Salmonella typhimurium was the organism from which the native plasmid was isolated by Stanley Cohen and Herbert Boyer to construct the first recombinant DNA in 1972. Therefore, th
