Analyzing DNA by gel electrophoresis allows re- searchers to first step in cloning a mouse last step in cloning a mouse Where are stem cells found? Pieces of DNA strand cut by restriction enzymes faster body cell and egg cell identify similarities and dif- ferences in teh genomes of different organisms isolate the donor's somat- ic and egg cells implant morula into a sur- rogate mother In early human embryos, umbilical cords and bone marrow of adults what is used in genetic en- gineering? Gene therapy technology what are the steps in cloning a mouse restriction enzymes, cloning, stem cells, vector, recombinant DNA Replacing defective genes with normal copies of the gene 1. isolating donor somatic and egg cells 2. enucleating the egg cell 3. transferring the nucleus of the somatic cell into the enucleated egg cell 4. chemcially stimiulating the new cell to divide until it becomes a morula 5. implanting the morula into a surrogate mother [Show Less]
