Question: 129: Match List-I with List-II :
| List-I | List-II |
|---|---|
| (a) Gene gun | (i) Replacement of a faulty gene by a normal healthy gene |
| (b) Gene therapy | (ii) Used for transfer of gene |
| (c) Gene cloning | (iii) Total DNA in the cells of an organism |
| (d) Genome | (iv) To obtain indentical copies of a particular DNA molecule |
Choose the correct answer from the options given below :
(1) (a) – (ii), (b) – (i), (c) – (iv), (d) – (iii)
(2) (a) – (i), (b) – (iii), (c) – (ii), (d) – (iv)
(3) (a) – (iv), (b) – (i), (c) – (iii), (d) – (ii)
(4) (a) – (ii), (b) – (iii), (c) – (iv), (d) – (i)
Answer: Option (1)
Explanation:
A gene gun is a biotechnological tool used to transfer foreign DNA into host cells by bombarding them with DNA-coated particles.
Hence, gene gun is correctly matched with used for transfer of gene.
Gene therapy is a technique in which a faulty or defective gene is replaced by a normal, healthy gene to treat genetic disorders.
Thus, gene therapy matches with replacement of a faulty gene by a normal healthy gene.
Gene cloning is the process used to produce identical copies of a specific DNA fragment.
Therefore, gene cloning is correctly matched with obtaining identical copies of a particular DNA molecule.
The genome refers to the complete set of DNA present in the cells of an organism.
Hence, genome is correctly matched with total DNA in the cells of an organism.
Thus, the correct matching is given in option (1).
