Question

Which of these is not the feature of a cloning vector? (A) Ori supporting high copy number (B) Selectable marker (C) Resistant to the action of restriction enzymes (D) Presence of cloning site

Tardigrade Admin · Accepted Answer

Cloning vectors should have many restriction enzyme recognition site but only one site for each restriction enzyme. Restriction enzyme identifies specific site on DNA and cuts at specific palindromic sequences from fragments so that the foreign DNA segment can be attached for cloning.
