Excerpt
Glossary: Animal bioreactor Transgenic animal that produces recombinant proteins in its milk, egg white, blood, urine, or seminal plasma. - Antibody Protein produced as part of the immune reaction to render harmless a foreign substance (e.g., bacteria) entering the body of an organism. - Cloning (a) Production of exact copies (clones) of a gene/genes (gene cloning). The DNA strand containing the gene of interest is cut into suitably sized pieces (fragmentation) and the gene of interest is linked to a piece of DNA (cloning vector). This vector is then introduced into cells (transfection) which are cultured in vitro and then screened for the presence of the gene of interest. (b) Production of genetically identical organisms by somatic cell nuclear transfer (SCNT). It involves the introduction of the nucleus of a somatic cell from the organism to be cloned into an enucleated egg cell.
