16.1 Cloning of a Gene
  • Using recombinant DNA technology, bacteria and viruses can be genetically engineered to clone a gene.
  • A genomic library contains bacteria or viruses that carry fragments of the DNA of a particular organism.
  • The polymerase chain reaction (PCR) makes multiple copies of DNA segments. Analysis of the DNA usually follows.
  1. What two enzymes are required to inject foreign DNA into a cell and what do they do?
    Answer
  2. What does PCR stand for and what is it used for?
    Answer
  3. What is DNA fingerprinting?
    Answer

16.2 Biotechnology Products
  • Bacteria, agricultural plants, and farm animals have been genetically engineered to produce commercially available products.
  • Human tissues and farm animals are being genetically engineered to serve as a source of organs for human transplant patients.
  • Agricultural plants and farm animals have been genetically engineered to improve their yield.
  • It is now possible to clone animals, and cloning is used to produce multiple copies of farm animals that have been genetically engineered.
