In cloning vectors, antibiotic resistant genes are helpful for
- A transfer of foreign gene to the host
- B selection of recombinants
- C making the host cells competent
- D cleaving of vector by REN
Answer & Solution
Correct Answer
(B) selection of recombinants
Step-by-step Solution
Detailed explanation
(B) selection of recombinants,
Antibotic resistance gene present in the vector is mainly used for the selection of transformed bacterial cell.The non-transformed cell failed to survive in the antibiotic containing media during the selection process.
