In gene therapy, a vector is c. A vehicle to deliver a gene. It is often a virus that has been genetically altered to carry normal human DNA. Vectors can be either viral or non-viral. Viral vectors are a tool commonly used by molecular biologists to deliver genetic material into cells. This process can be performed inside a living organism (in vivo) or in cell culture (in vitro). Examples of vectors include plasmids, bacteriophages, cosmids, and yeast artificial chromosomes; viruses are often used, for example retroviruses, adenoviruses, adeno-associated viruses, lentiviruses.
