During recombinant DNA procedure, vector provides

During recombinant DNA procedure, vector provides origin of replication. The origin of replication is a specific DNA sequence on the vector that serves as a starting point for DNA replication. This means that when the vector with the foreign DNA insert is introduced into a host organism, such as a bacterium, the host organism's DNA replication machinery can recognize the origin of replication on the vector and initiate the replication of the entire vector, including the foreign DNA insert.
