What is it?• Species identification can be difficult.
What is it?
What is it?
Modern genetics techniques can be used to identify species.
• All living (or once-living) things contain DNA.
• Different species have different DNA sequences.
• Polymerase chain reaction (PCR) can make millions of copies of specific DNA sequences, which can then be analyzed.

Bio 261: Nucleic AcidsFinal Project
• Each student:– received a swab of cells
from an unknown organism.– designed and executed an
experiment using PCR to identify the source species.
Benefits to students:• Challenging and fun• Authentic laboratory experience; real-world
problem-solving• Opportunity to demonstrate marketable skills
