  1. DNA and Biotechnology Chapter 5

  2. Making Recombinant DNA restriction enzyme (cut) DNA ligase (paste) mix Fig. 16-2, p. 242

  3. Genetic engineering • A laboratory process by which deliberate changes are introduced into an individual’s genome • Genetically modified organisms (GMOs) • Individuals containing modified genes from the same species or a different species
