Scientists have developed a way to alter genes in
sheep and insert new ones with unprecedented
precision, a step toward creating healthier
livestock and using animals as organ banks. This
is the first time so-called gene targeting has
been done in a mammal other than a mouse. They
altered the DNA in sheep cells, and then used the
cells to create sheep by cloning. Three female
sheep produced last year with genetic changes are
still alive. |
