  5. DNA fragments can be separated by electrophoresis and analyzed to identify alleles.
  6. DNA can be used to determine if two samples of DNA are from the same source.
  7. DNA sequencing can be done by the chain termination method.
  8. Some somatic cells remain and can generate a whole organism.
  9. Mammalian cells may be or .
