Description: The xenovector is a type of biological vector designed to transfer genetic material between different species, thus facilitating genetic manipulation and research in biotechnology. Unlike traditional vectors, which are usually limited to transfers within the same species or to closely related species, xenovectors allow for gene transfer between organisms that may be genetically distant. This is achieved through genetic engineering, where viruses or plasmids are modified to carry the desired genetic material. Xenovectors are essential in the creation of genetically modified organisms (GMOs), in gene therapy, and in the production of recombinant proteins. Their ability to cross evolutionary barriers greatly expands the possibilities in biomedical research and agriculture, allowing for the introduction of desired traits in crops or in animal models for disease studies. In summary, xenovectors are fundamental tools in modern biotechnology, offering an innovative approach to the transfer of genetic information between diverse species.
