Question

Match the LIST-I (Species) with LIST-II (Products under development): 
\[ \begin{array}{|l|l|} \hline \textbf{LIST I (Species)} & \textbf{LIST II (Products under development)} \\ \hline A. \ \text{Cow} & I. \ \text{Antithrombin II} \\ B. \ \text{Goat} & II. \ \text{Insulin} \\ C. \ \text{Sheep} & III. \ \text{Fibrinogen} \\ D. \ \text{Chicken} & IV. \ \text{Lactoferrin} \\ \hline \end{array} \]
Choose the correct answer from the options given below: 
 

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

Hint:

Remember: Goats → Antithrombin II, Sheep → Fibrinogen, Cows → Lactoferrin, Chickens → Insulin.

Answer 1

The Correct Option is A

Step 1: Understand transgenic species products.
Scientists use transgenic animals to produce therapeutic proteins. Each animal species can be genetically engineered to express specific products in their milk or eggs.
Step 2: Match correctly.
- Cow → Lactoferrin (IV): Lactoferrin is produced from cow’s milk.
- Goat → Antithrombin II (I): Goats have been engineered to produce this anticoagulant protein in their milk.
- Sheep → Fibrinogen (III): Sheep are used to produce blood-clotting factors like fibrinogen.
- Chicken → Insulin (II): Chickens have been explored for producing insulin in eggs.
Step 3: Verify with options.
Option (A) matches all correctly.
Step 4: Conclusion.
The correct match is Cow - IV, Goat - I, Sheep - III, Chicken - II.
