Cloning vectors are DNA molecules used to insert fragments of foreign DNA into a host cell. The vector still has the properties of multiplying and self-replication. These vectors introduce foreign DNA into the host cells, which then may divide in large...

A cloning vector is a small DNA vehicle that carries a foreign DNA fragment. The insertion of the fragment into the cloning vector is carried out by treating the vehicle and the foreign DNA with the same restriction enzyme, then ligating the fragments...
