Chapter 19 Viruses Review
  1. Viruses are intracellular parasites and can reproduce only within cells.
     
     
     
     
  2. Bacterial viruses ( ) go through two alternative reproductive mechanisms.
     
     
     
     
    • The lytic cycle describes a phage.
       
       
       
       
    • The lysogenic cycle describes a phage.
     
     
     
     
  3. Animal viruses include RNA viruses, some of which are such as HIV that contain their own transcriptase.

Chapter 20 Biotechnology Review
  1. DNA cloning (making copies of a DNA segment) often makes use of a bacterial .
     
     
     
     
  2. Bacterial enzymes can be used to make DNA.
     
     
     
     
  3. The recombinant DNA can then be in host bacteria and stored in genomic libraries.
     
     
     
     
  4. Restriction fragment can detect differences in DNA by using gel electrophoresis to separate restriction fragments of different lengths.
     
     
     
     
  5. The polymerase reaction (PCR) can make copies of a segment of DNA in .
     
     
     
     
  6. DNA sequencing can be done by the chain termination method.
     
     
     
     
  7. DNA can be used to study patterns of gene expression of an organism.
     
     
     
     
  8. Some somatic cells remain and can generate a whole organism.
     
     
     
     
  9. Mammalian cells can be harvested from the stage during embryonic development, or from some adult tissues, and can differentiate into several types of specialized cells.
     
     
     
     
  10. One technique for making of animals is nuclear , which has been used to clone mammals such as Dolly and Copy.
