Cloning vector is a small piece of DNA, taken from a virus, a plasmid or the cell of a higher organism that can be stably maintained in an organism. pUC 18 is the most popular E. coli cloning vector.
An expression vector or construct, is usually a plasmid or virus designed for gene expression in cells. The vector is used to introduce a specific gene into a target cell, and can commandeer the cell's mechanism for protein synthesis to produce the protein encoded by the gene.
