A: Getting the gene into the right place, we're a little far away from that. But the technology of genetic transformation is evolving all the time and it's better now than it ever was and it's going to continue to evolve. Right now the biggest advances that we've made is to be able to pick out those individual cells that have been transformed in the most efficient way possible and then only generating and only continuing those lines that have good expression and good stable Mendelian genetics. Those are the things that we're able to do better now than we ever have before and that will continue to evolve.
