NEET Zoology Genetic Engineering MCQ Question
What is the role of the origin of replication (ori) in a cloning vector?
It initiates replication and controls the copy number of linked DNA.
It serves as a selectable marker for identifying transformants.
It ensures the growth of non-transformants in a culture.
It provides a mechanism for protein synthesis within the host.
Correct Answer
Detailed Explanation
The origin of replication (ori) is a sequence from where replication starts and is responsible for controlling the copy number of the linked DNA, allowing for the recovery of many copies of the target DNA.
