Virginia’s CTE Resource Center

Describe the technologies used in identifying and analyzing DNA from a crime scene.

Definition

Description should include
  • polymerase chain reaction (PCR)
  • short tandem repeat (STR) analysis
  • electrophoresis
  • Y-STR testing
  • mitochondrial DNA testing.

Process/Skill Questions

  • What are the appropriate uses for each of the DNA analysis techniques?
