​The following table enlists different ways of carrying out reverse genetics (Column X) and different strategies to achieve the same (Column Y).​

​Which one of the following options is a correct match between Column X and Y?​

Correct option is B

Explanation-

Reverse genetics starts from a known gene and investigates what phenotype arises when the gene is altered.
The table contains:
                    1.  Column X: Different methods of reverse genetics
                    2.  Column Y: Specific tools/strategies used to perform them

Matching Column X with Column Y
A. Random mutagenesis  
This involves introducing mutations without targeting a specific site.
iv. UV mutagenesis → UV light causes random DNA damage.
ii. Transposable elements → Insert randomly into the genome.
So correct match - A → iv or ii

B. Targeted mutagenesis
This refers to deliberate modification of a specific gene.
iii. Homologous recombination → Allows precise replacement/insertion of gene.
v. CRISPR → Enables targeted DNA editing at specific sites.
So correct match - B → iii or v

C. Phenocopying
This involves mimicking a genetic mutation using non-genetic means (e.g., temporarily reducing gene expression).
i. RNAi (RNA interference) → Silences gene expression, simulating loss-of-function phenotype without mutating DNA.
So correct match - C → i

Correct option b - ​A - ii and iv; B - iii and v; C - i
