@nikipedia there is a lot more that can be read on this subject, but I find it quite interesting and opens a whole new world of ways to combat diseases in not only humans but animals as well.
_Transgenic Animals
A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome. The foreign gene is constructed using recombinant DNA methodology. In addition to a structural gene, the DNA usually includes other sequences to enable it
* to be incorporated into the DNA of the host and
* to be expressed correctly by the cells of the host.
* Transgenic sheep and goats have been produced that express foreign proteins in their milk.
* Transgenic chickens are now able to synthesize human proteins in the “white” of the eggs. _
This is quite interesting and possibly one of the most important discoveries to mankind.
