In this lab, students will:

  • Discover/review the location and the role of DNA in our bodies
  • Perform gel electrophoresis to compare DNA from suspects to DNA found at the crime scene
  • Explore how genetic signatures are used in forensics and other applications
  • Discuss how environmental and genetic factors influence organisms

Standards:

  • 8-LS1-5. Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
  • 8-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
