Question

Match List I with List II : 

List I	List II
A. Genetically modified organism  B. Thermostable DNA polymerase  C. Ti plasmid  D. pBR322	I. Agrobacterium tumefaciens  II. Bt cotton  III. Thermus aquaticus  IV. Escherichia coli

Choose the correct answer from the options given below :

• A. A-II, B-III, C-I, D-IV
• B. A-I, B-IV, C-III, D-II
• C. A-I, B-II, C-IV, D-III
• D. A-II, B-I, C-IV, D-III

Hint:

Associate \textbf{T}hermostable with {\textbf{T}hermus aquaticus} and \textbf{Ti} plasmid with {\textbf{A}grobacterium} (The Natural Genetic Engineer).

Answer 1

The Correct Option is A

To solve this question, we need to match each item from List I with the correct item from List II based on biological relevance. Let's analyze each pair:

1. Genetically modified organism (GMO): This term commonly refers to organisms that have been modified using biotechnology to express certain desired traits. In agriculture, Bt cotton is a well-known GMO, engineered to express the Bacillus thuringiensis toxin to deter pests. Thus, A matches with II.
2. Thermostable DNA polymerase: This enzyme is crucial for polymerase chain reactions (PCR) due to its ability to withstand high temperatures. The most famous thermostable DNA polymerase comes from the bacterium Thermus aquaticus. Therefore, B matches with III.
3. Ti plasmid: This plasmid is derived from Agrobacterium tumefaciens and is utilized in genetic engineering to introduce new genes into plant cells. Hence, C is matched with I.
4. pBR322: This is a plasmid vector used in cloning experiments, derived from Escherichia coli. Thus, D matches with IV.

Based on this analysis, the correct option is A-II, B-III, C-I, D-IV.
