Choose the correct answer from the options given below :
Matching Biotechnology Concepts: List I and List II
This question requires matching specific biotechnology terms in List I with their corresponding entities or examples in List II.
Understanding the Matches
Here’s a breakdown of the correct matches:
- A. Genetically modified organism corresponds to II. Bt cotton. Bt cotton is engineered to produce an insecticide, making it a genetically modified organism (GMO).
- B. Thermostable DNA polymerase corresponds to III. Thermus aquaticus. This bacterium is the source of Taq polymerase, a heat-resistant DNA polymerase essential for PCR.
- C. Ti plasmid corresponds to I. Agrobacterium tumefaciens. The Ti plasmid, naturally found in this bacterium, is widely used for genetic transformation in plants.
- D. pBR322 corresponds to IV. Escherichia coli. pBR322 is a commonly used plasmid vector, often propagated and manipulated within E. coli.
