Origin of Replication (ori) is a sequence from where replication starts and when any piece of DNA linked to this sequence, can be made to replicate within the host cells.

This sequence is responsible for controlling the copy number of the linked DNA. So, if one wants to recover many copies of the target DNA it should be cloned in a vector whose origin supports high copy number.
