AIIMS 2017 Botany Gene Expression Match the Following Question
Match the following columns
Column I I. Multigenes II. Inducible genes III. Overlapping genes IV. Structural genes
Column II (i) transposons (ii) insulin (iii) B, E, and K in ϕ×174 (iv) snRNA (v) globin gene (vi) nitrate reductase
I - (i), II - (iii), III - (v), IV - (ii)
I - (v), II - (vi), III - (iii), IV - (ii)
I - (iv), II - (v), III - (vi), IV - (i)
I - (i), II - (ii), III - (v), IV - (vi)
Correct Answer
Detailed Explanation
Option C is correct because it accurately matches the definitions of the gene types with their corresponding examples: multigenes (I) refer to snRNA (iv), which are often present in multiple copies; inducible genes (II) correspond to the globin gene (v), as they can be expressed in response to specific stimuli; overlapping genes (III) are exemplified by B, E, and K in ϕ×174 (iii), which share sequences; and structural genes (IV) are represented by insulin (ii), a key structural protein.
Other options are incorrect because they misalign the gene types with their examples; for instance, option A incorrectly associates multigenes with transposons (i), which are mobile genetic elements rather than gene types, and option B mismatches inducible genes with nitrate reductase (vi), which is typically constitutively expressed. Understanding these classifications helps in grasping gene regulation and expression patterns in molecular biology.
