Which of the following are used in gene cloning?
Correct answer: D. Plasmids
- A. Nucleoids
- B. Lomasomes
- C. Mesosome
- D. Plasmids
Explanation
Plasmid is a small circular double-stranded DNA molecule present in the cytoplasm of the bacterial cell. It can replicate independently of the bacterial chromosome. Due to this characteristic of plasmid, it is used as the vector (vectors are for the transferring of a piece of DNA to the target gene) in gene cloning.
