THE ULTIMATE CLUE, MY DEAR WATSON: DNA FINGERPRINTING Students
learn practical applications of DNA profiling in today's
forensic science and the future's many possibilities. While
viewing the video, students delve into the problems of
extracting ancient DNA from fossils. These molecular biologists
use DNA profiling to sequence pieces of the dinosaurs' genome.
After viewing the video, students will simulate DNA profiling
with electrophoresis gel to solve a possible baby mix-up at the
hospital. NOVA: The Real Jurassic Park Students will be able to:
- Explain the steps of DNA Profiling - Describe the possible
usefulness of DNA Profiling to our society - Contrast extracting
ancient DNA from fossils to modern DNA from blood and other
cells of organisms. Per group of two: - Copies of the lab "Will
the Real Baby Smith Please Speak Up!" - Glue or tape To prepare
students for the video, explain the steps of extracting and
profiling DNA. Explain how DNA is extracted and isolated from
cells. Cell membranes are lysed wit
