NEET Zoology Genetic Engineering Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Insertional Inactivation | (i) β-galactosidase gene |
| (b) Selectable Marker | (ii) Antibiotic resistance |
| (c) Chromogenic Substrate | (iii) Blue colonies |
| (d) Recombinant DNA | (iv) Alien DNA insertion |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-i, d-ii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
Insertional inactivation involves the interruption of the β-galactosidase gene by alien DNA, resulting in blue colonies on chromogenic substrates when the plasmid is successful. Selectable markers help differentiate recombinants based on antibiotic resistance, thus confirming their identity.
