Question

In genetic engineering, the term vector is applied for

• A. Plasmids
• B. Active viruses
• C. Source of DNA
• D. Cell which receives DNA

Answer 1

The correct option is A Plasmids

In molecular cloning, a vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated and/or expressed. A vector containing foreign DNA is termed recombinant DNA. The four major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes. Of these, the most commonly used vectors are plasmids.

Therefore, the correct answer is option A.
