NEET · BiologyEasy
Which of the following is commonly used as a cloning vector in biotechnology?
- A.Plasmid
- B.Ribosome
- C.Lysosome
- D.Mitochondrion
Show correct answer & step-by-step solution
Correct answer: A — Plasmid
Solution
- A cloning vector must be capable of autonomous replication within a host cell.
- Plasmids are naturally occurring circular DNA molecules found in bacteria.
- They are engineered to contain antibiotic resistance genes and multiple cloning sites.
- Hence the answer is (A).
