BIOMEDICAL APPLICATIONS OF GENETICALLY ENGINEERED AND CLONED ANIMALS
Biomedicine is the application of the principles of the natural sciences, especially biochemistry, molecular biology, and microbiology, to human and
veterinary clinical medicine. The field of biomedicine offers tremendous potential to treat pain and suffering in humans and animals worldwide.
Biomedical research using genetically engineered and cloned animals is being conducted to produce therapeutic drugs for the treatment of human
diseases, for the production of organs for human transplantation, and to study the effects that individual genes on body function.
Scientists have used the techniques of cloning and genetic engineering as tools to advance this field of study. Often these terms are lumped together
as being the same, but they are actually quite different. Cloning is the process of replicating an exact genetic copy of a plant or animal. On the
other hand, genetic engineering is the introduction of DNA sequences into the genome of a living organism using naturally-occurring enzymes to "cut"
a fragment of DNA from one organism and "paste" it into the genome of another. These terms are often affiliated with each other because cloning can
be used as a vehicle to increase the efficiency of genetic engineering. Cloning allows for the production of animals from cells which have undergone
precise, characterized modifications to their genome, or genetic background.

OK according to this article cloning can act as a vehicle for genetic engineering, this may be what the guy in the clip was refering to, instead of
just your everyday cloning. So it looks like cows have been geneticly modified as well as cloned, with human characteristics.
