Which of the following is the suitable vector to be incorporated with the large external DNA fragment?
Correct answer: A. Small size vector
- A. Small size vector
- B. Large size vector
- C. Large size vector with no origin of replication.
- D. Small size vector with no origin of replication.
Explanation
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. A small size is the suitable vector to be incorporated with the large external DNA fragment because it should be small in size so that it can easily integrate into the host cell. It should be capable of inserting a large segment of DNA. It should possess multiple cloning sites.
