		Frequency of cutting: Because of their restriction site specificity, the restriction endonucleases cut DNA into fragments whose average length is determined by the number of base pairs in the restriction site (and to a lesser extent by the ratio of bases in the DNA).
		Another trick that is sometimes used is to eliminate a naturally-occurring cut sites (or generate a new cut site) by changing the third bases of codons in ways that eliminate (or generate) restriction endonuclease cut sites without altering the amino acid coding of genes carried in the vector.
		Multiple cloning sites: Most sophisticated modern vectors contain multiple cloning sites, which consist of a short stretches of artificially synthesized DNA containing cut sites for a number of different restriction endonucleases located side by side (figure 9.7).

		Another common cloning strategy employed, blunt-end ligation, particularly useful when working with incompatible ends, is inefficient when applied to PCR fragments because many polymerases used in PCR, as it happens, add additional nucleotides to the ends of the fragments, creating staggered ends.
		The vector is designed such that the cloning site is embedded in the lamdba repressor gene, cI, which is engineered to repress the promoter for the tetracycline-resistance gene.
		The pPMG-LIC Bacterial Cloning Kit has a LIC site surrounded by SP6 and T7 polymerase promoters for in vitro transcription studies, f1 origin of replication for the generation of single-stranded templates, and several unique cloning sites to facilitate the retrieval of inserts.

	The Scientist : Honing Your Cloning
		The location of the attL, attR, attB, and attP sites in the vectors maintains the correct orientation of the cloned insert as it moves from the Entry to the Destination Vector; the precise positioning of the recombination sites maintains the correct reading frame for the protein fusions.
		The pQE series of vectors does not incorporate proteolytic sites to allow separation of the protein of interest from the tag proteins (although introducing such sites during cloning is feasible).
		Genes cloned in these vectors are transcriptionally inactive until the system is activated with the ecdysone analogs muristerone A or ponasterone A; over 1,000-fold activation has been observed in stable cell lines.

	Support, restriction enzymes: Cleavage of Restriction Targets Located in Close Vicinity within pUC19 Multiple Cloning ...
		Double digestions within multiple cloning sites (MCS) are often ineffective when the DNA target sequences are in close vicinity, or they are too close to the end of a DNA molecule (see Table "Cleavage Efficiency Close to the Termini of PCR Fragments").
		Nevertheless, it is often necessary to perform effective double digestions within the cloning sites in which restriction targets are in close vicinity.
		Thus, the first reaction should be performed with a restriction enzyme that cleaves inefficiently close to the end of DNA, while the second digestion should be performed with a restriction enzyme which tolerates a close proximity to the DNA end.

	Interpretation of VecScreen Results
		The presence of cloning sites, especially of specific site(s) known to have been used in cloning the source DNA/RNA, is strong evidence that the matching segment comes from a vector, linker, adapter, or primer.
		Even short matches to a multiple cloning site (MCS), or to the sequence flanking a cloning site of a vector, are strong evidence that the segment has a foreign origin.
		If the cloning history is unknown, a restriction site analysis on the matching segment and the flanking sequence may locate cloning sites that are good candidates for the boundary of the foreign DNA.

		Figure 9.2 is an example of this, except that it is limited to cut sites that only occur once in the entire circular genome of the plasmid.
		Another trick that is sometimes used is to eliminate naturally-occurring cut sites (or generate new cut sites) by changing the third bases of codons in ways that eliminate (or generate) restriction endonuclease cut sites without altering the amino acid coding of genes carried in the vector.

	Multiple cloning site - Wikipedia, the free encyclopedia
		A multiple cloning site (MCS), also called a polylinker, is a short segment of DNA which contains many (usually 20+) restriction sites - a standard feature of engineered plasmids.
		MCSs are commonly used during procedures involving molecular cloning or subcloning.
		Extremely useful in biotechnology, bioengineering, and molecular genetics, MCSs let a biotechnologist insert a piece of DNA or several pieces of DNA into the region of the MCS.

		Three cassettes for the expression of a cloned coding sequence behind different promoters have been modified; combinations of these cassettes can be excised with Not I, and sequentially cloned into the transformation vector in a procedure that removes the first cloning site.
		This procedure left a Not I site, into which one of three plant expression cassettes was ligated, and removed a number of restriction sites, ensuring that the multiple cloning sites of the expression cassettes contained sites unique to the resulting plasmid.
		To assemble any combination of cassettes into the Eco RI or Not I sites, non-palindromic conversion adaptors (Stover et al., 1987) are first used to clone in any Not I-excised cassette into the Eco RI site in a process that destroys the Not I site.

		However, previously described systems utilize multiple plasmids and are not efficient enough to allow detection of insertion events in the absence of a selection [14-16].
