Question

Quizplus · Accepted Answer

Cloning vectors are designed to replicate within a host cell, and a high copy number ensures that many copies of the vector (and thus the inserted DNA) are produced. Antibiotic resistance genes are used as selectable markers to identify host cells that have successfully taken up the vector.
