It is possible to get DNA from the skeleton of an American Indian who died before 1492. I can guarantee you that there will not be any Semitic DNA in it. It will all be similar to Northern Siberian DNA. The Book of Mormon clearly says that American Indians are descended from Semitic migrants. They are not.The LDS church would pay them handsomely to get a single strand of hair. What you say is balderdash. There is no Semitic blood in the pre-Columbian America's.
