  1. DNA cloning (making copies of a DNA segment) often makes use of a bacterial          .

  2. Bacterial              enzymes can be used to make              DNA which can be cloned in host bacteria.

  3.        are DNA copies made from processed mRNAs which contain only        .

  4. The polymerase        reaction (PCR) can make copies of a segment of DNA in        .

  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              .

  10. One technique for making         of animals is nuclear                  , which has been used to clone mammals such as Dolly and         Copy.
