It involves using a variety of laboratory methods to put a piece of DNA into a bacterial or yeast cell. Generally speaking, expression of a foreign gene requires restructuring the gene to include sequences that are required for producing an mRNA molecule that can be used by the host's translational apparatus (e.g. Bethesda, MD 20894, Web Policies DNA colony hybridization to identify.
