Correct answer: B. DNA fingerprinting
- A. Cloning
- B. DNA fingerprinting
- C. Restriction Analysis
- D. Polymorphism
- E. Gene sequencing
Explanation
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. DNA fingerprinting is also used to establish paternity. The figure below shows a DNA fingerprint:
