- ribosomes
- lysosomes
- microbodies
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding gene transfer.
In genetic engineering, plasmids are commonly used as vectors to transfer genes into target cells. Plasmids are circular DNA molecules that can replicate independently of chromosomal DNA.
Step 2: Analyzing the options.
(A) plasmids: Correct. Plasmids are widely used as vectors in genetic engineering to transfer genes.
(B) ribosomes: Incorrect. Ribosomes are involved in protein synthesis, not gene transfer.
(C) lysosomes: Incorrect. Lysosomes are involved in digestion within the cell and do not participate in gene transfer.
(D) microbodies: Incorrect. Microbodies (like peroxisomes) are involved in metabolic processes but not in gene transfer.
Step 3: Conclusion.
The correct answer is (A) plasmids, as they are commonly used in genetic engineering for gene transfer.
