The sequence that controls the copy number of the linked DNA in the vector, is termed :

The copy number of linked DNA to the vector is controlled by the Ori site of vector.

(1) Selectable markers are genes within a cloning vector essential for selection of transformed recombinants and elimination of non-recombinants.

(3) A palindromic DNA sequence reads the same in 3’ to 5’ direction and 5’ to 3’ direction. The recognition sites
of restriction enzymes are usually palindromic.

(4) Recognition site is the specific sequence of nucleotides of DNA identified by a specific restriction endonuclease. It is usually palindromic.
