Plаsmid clоning vectоrs аre engineered tо hаve cloning sites for foreign DNA fragments that consist of a series of cutting sites for different restriction endonucleases. This allows DNA fragments that are generated by a variety of restriction endonucleases to be incorporated into the vectors. These multiple arrays of restriction enzyme sites are called:
