Write the role of 'ori' and 'restriction site' in a cloning vector PBR322.

Text Solution

Verified by Experts

Ori is the site where replication starts. This site is responsible for controlling the copy number of a vector. Restriction site is the site of ligation of alien/foreign DNA in the vector, in one of the two antibiotic resistance sites or coding sequence of `beta`-galactosidase.
