Question

Match the Column-I with Column-II and select the correct option.
Column – I Column – II
a) Female banded Krait i) Humulin
b) Pancreas from dog ii) DNA sample
c) Hair root of human iii) Insulin extracted and purified
d) {E. coli} iv) DNA probe

• A. a–i, b–ii, c–iv, d–iii
• B. a–ii, b–i, c–iii, d–iv
• C. a–iii, b–iv, c–ii, d–i
• D. a–iv, b–iii, c–ii, d–i

Hint:

{{E. coli} → Humulin}, {Hair root → DNA sample}.

Answer 1

The Correct Option is D

Step 1: Understanding applications of biological materials.
Different biological sources are used for specific purposes in biotechnology and medical science.

Step 2: Correct matching.
Female banded krait venom is used to prepare a DNA probe.
Pancreas from dog was historically used for insulin extraction and purification.
Hair root of human is commonly used as a DNA sample.
{E. coli} is genetically engineered to produce Humulin (human insulin).

Step 3: Conclusion.
Thus, the correct matching is a–iv, b–iii, c–ii, d–i which corresponds to option (D).
